Hi Patrick!! I'm brand new to the forum, but I've been checking it out for a bit... First of all, hats off for the bus build – I'm sure I'm not the first to tell you and definitely won't be the last! lol I'm reaching out because I'm nearing the end of my truck conversion – quick intro, it's a Mercedes PL 709d van... After 2 years of work we're finally seeing the light at the end of the tunnel!!!! and yeah when you love a project you don't mind the effort... I'm hoping you could help me put together the homologation file? There are a few points I'm struggling to understand – specifically weight distribution (especially the interior storage), body certification, and other bits and pieces... Thanks in advance See you

Hey skass,

I've been following your project from the start, right up to the 'cut finger'🏴‍☠️

That's really, really beautiful work 😎

On the other hand, I skipped the comments and didn't verify that you'd done everything to code, but you shouldn't have any issues with Véritas.

You might just have a problem down the road with your rigid PVC wastewater line—it could crack when rolling.

Anyway, for the storage boxes, you just need to fill out the DRIRE form. You measure the distance of your boxes relative to the front axle, you fill in the formula: mass of each box × distance relative to the front axle --> that gives you a moment (B)

you add up all the moments (B) divided by the vehicle's wheelbase and you get the max weight on the rear axle

you do your vehicle's GVWR minus the max rear axle weight, and you get the max front axle weight.

you compare all that with the manufacturer's specs (on the red bar)

you need to weigh the front and rear axles and the empty vehicle before all that.

the simplest would have been to weigh your build as you went (that's what I did, but my build is very, very, very basic😄) but with the weighings you can manage it.

don't worry, I spent 3 days on it and redid it 3 times (had a little issue with exceeding the max manufacturer weight with the TELMA weight😮), but you don't have a TELMA😉

with a 709, it's simpler than a bus, because you don't have a front overhang, but on the other hand, you can't juggle things to lighten the rear by adding weight ahead of the front axle (negative distance)

anyway, for the body certificate, I don't see why ??? you simply request a written reclassification certificate of your truck as a caravan-spec vehicle from MERCEDES FRANCE.

trifles...? they don't exist in a DRIRE file 😏😏😏

Well done with your project GX47

Congratulations!! I've watched your project evolve over time, you're doing great work. The problem with getting official approval is that you really need to first understand the regulations better and design your conversion based on what's required. If you build it and then pray it passes inspection... Just one detail by the way—there must be no sharp corners around where passengers will be. Check that you have at least 45 cm of clearance everywhere. One thing that could catch you out is the lack of an emergency exit in your bathroom, unless you have less than 2 meters from the main exit door handle to the bathroom door handle. I didn't see the required permanent ventilation openings that can't be blocked—both low and high. That's what I noticed at a quick glance. I have the book with the current regulations. Give me a call if you need it. 0664423159.

😉Hi SKASS,

I've got just one thing to say 😎CONGRATULATIONS😎. What a joy to see the work in photos—it helps so much.
SK Skass ·
hey well, I thought I'd slip through unnoticed on this forum..... well, that didn't work out!!! thanks for your messages anyway GX47 I think I got what you explained to me, today I went to weigh the truck for certification and we're all good - we've got plenty of margin compared to the weights shown in red! I'm gonna try to fill out that document, if anything comes up I'll let you know, thanks a lot!

as for the standards we've been following them from the start, and it's not easy to meet everything while getting the layout we want in the end! but it's alright with patience we always manage.... the bathroom emergency exit is fine, it's 1.74m from handle to handle, and there's also continuous mechanical ventilation... what I'm hoping is that I can get 5 seats certified instead of 3 on the registration, normally it should go through but yeah with those lovely officials from the DRIRE you always gotta be careful, we'll see!

well then tomorrow it's the Véritas inspection, the beginning of the end...

have a good evening talk soon

Hi everyone, at the risk of posting something that might be redundant, I'm looking for ideas on bus conversion layouts and photos of converted bus interiors. So if you have any links handy... I've just acquired an S45 in great condition. I don't plan to move it around much—it's mainly about being able to move it around several hectares of land from time to time, depending on the season. But there will also be some occasional trips outside, so I plan to keep it street-legal (with inspections). Thanks for your responses! !

Hey, we're Plume and Julien—we just discovered this site! We've been thinking about traveling for a year and have looked at several options. We think a bus would be the best choice for us. We like having space, and we have two big dogs. Plus, since it's going to be our home for a year, we've already found a bus we like. But we're not really sure how to go about getting the campervan certification. Since we want to travel far, it needs to meet campervan 'standards.' We're young (23 years old), so we don't have a lot of money, but we're hard workers. We'd like to know if we can convert it ourselves and what we need to do to meet the standards for the technical inspection. Any advice, tips, and tricks would be welcome—here or on our MSN plume_dargent@hotmail.com. It would be great to chat with people who are passionate about this way of traveling! 😉

Salut,

alors, pour se lancer dans l'aventure, il faut commencer par le bon bout.

pour apprendre la musique, on commence par le solfege...

pour ammenager un vehicule, on se plonge dans les normes!

c'est pas compliqué, un peu rebarbatif au debut, mais pas compliqué!

donc, tu vas sur le site de l'afnor (tu trouveras les coordonées quelques posts plus haut) et tu commande le guide d'ammenagement des vehicules de loisirs.

tu le lit (tout!)

apres, tu survole ce sujet de discution depuis le debut (ou au moins depuis la page 19 et le post sur la nouvelle reglementation).

tu auras une idée relativement complete apres cela, et tu pourras poser les questions complementaires necessaires a TON projet, car chaque projet est different (toi tu veux vivre dedans, alors que moi, je veux partir en vacances avec mes trois enfants!)

pour l'instant, il est dur de t'epauler plus. tu part de trop loin. il te faut un minimum de connaissances et une approche des bases. ensuite, toute la communauté sera la pour te conseiller et te permettre de faire aboutir ton projet.

comprends bien! je ne te refoule pas! bien au contraire! je suis un des piliers de ce sujet de discussion (je l'ai créé il y a 2 ans maintenant). mais le parcours initiatique commence par la....

si tu te met devant le piano sans solfege avant, c'est mort!

les explications que nous pourrions te donner seront trop complexes par post si tu n'a pas une legere connaissance.

heureux de compter un passioné de plus sur ce forum!

au fait, c'est quoi comme modele, le bus que tu as reperé?

PATRICK26

et si tu veux qu'on en discute, tu me passes en messagerie privée un numero de tel fixe et on se tel un de ces soirs pour en parler...

Ne te vexe pas !!😕 Le projet de bus sur la base duquel onn a travaillé est parti à la ferraille et j'ai appellé le ferrailleur trop tard...Déjà passé au broyeur! Donc je me suis rabatu sur un setra S 215 RL et j'ai du remanier un peu les SUPERBES plans que tu m'avais fait sur PC. Hélas, je n'ai pas tes connaissances en matière de création artistique assitée par ordinateur. Du coup, j'ai fait un hybride de tes idées et de mon plan. Mon four est toujours sous le rechaud! J'ai rajouté 15 cm entre la paroie et le plan de travail car la jonction sol paroie est arondie. Ainsi, je fait une gaine technique pour mes alims et évacuations et surtout, je peux encastrer completement sous le plan de travail mon lave linge. Je ferais peut etre pareil en face si mon seche linge ne passe pas en profondeur. Tu vois on a pas bossé pour rien, je peux me laisser influencer par tes résolument bonnes idées!! Par contre j'ai la tête bien dure aussi et j'ai remis les sieges tout à l'avant et j'ai re-supprimé la porte millieu. J'ai gardé des WC en long et je ferais sans doute un petit lave main d'angle dedans. Le fait d'avoir avancé mon plan de travail coté évier me permet aussi de l'aligner avec la salle d'eau, plus de vilaine cassure et possibilité de mettre un meuble avec plan de travail et vasque en 70 de large, du luxe pour un camping car!! Voilà, tu vois bien encore une fois qu'on a pas travaillé pour rien, cela dit je suis encore ouvert à toutes critiques contructives! Merci encore de ta compétence et à très bientot j'èspère. P.S: Ne cherche plus ton crayon, c'est moi qui l'ai emporté par indvertance, désolé, je te le rend le + vite possible !!

Hello,

je profite de ton poste pour relancer mon sondage qui decidement ne trouve pas de reponses🏴‍☠️ c'est le sondage sur les WC:

qu'est ce que tu vas installer exactement ? quelle va etre l'utilisation de ton camping car ? et la question du neophyte: quels sont les avantages et les inconvenients de ton systeme ?

Bon vu que t'as le bus et le plan, y'a plus qu'a comme on dit ! bon courrage ;-)

Salut,

je peux donner mon avis ?

oui, non, oui bon ben en fait c'est pas sur l'aménagement, c'est juste sur les sièges : il y à 10 places assises, la DRIRE risque de te refuser ton bus pour çà, c'est ce qui m'était arrivé, j'avais pourtant désigné avec une étiquette les places route comme spécifié dans les textes, mais l'ingénieur à refusé car ce sont des sièges origine route, il à falu que je démonte le siège à coté du conducteur et déclare l'emplacement en "espace matériel" pour 85 kg de charge (75kg plus le poids du siège) et aussi que je mette une étiquette "places inutilisable en route" sur la banquette-lit de 4 places.

j'ai bien essayé de négocier avec un panonceau comme sur la banquette, mais non! rien ne m'empèchait de prendre 9 passagers. j'ai pas voulu être con (quant tu veux un coup de tampon tu reste cool) mais j'avais envie de dire que rien m'empèchais d'emmener 14 personnes non plus (sans compter les clandestins accrochés au chassis😄)

😠 pourquoi démonter un siège d'origine et laisser une banquette empreintée de l'estafette cc de mon père ???

mais bon voilà juste une petite mise en garde pour prévenir @+

Le WC que je compte installer est un sanimarin 35. Avantages: le reservoir d'eau noires peut etre deporté jusqu'a 25 metres du WC, pas d'utilisation de produits chimiques. Inconvéniants: conso d'eau et d'éléctricité supérieurs aux WC a sassette et autres. Cycle eco: 0.8 litres et cycle complet: 1.06 litres. Je compte utiliser mon camping car bus que pour vacances et week end. Prévu pour 6 permanents et 8 personnes en occasionnel.

Judicieuse remarge cher GX!! C'est de ma faute, j'ai omis de préciser que j'ai piqué un plan de Vanhool pour avoir un idée de l'encombrement à l'avant du bus. Je ne suis pas embété à enlever le siege du guide car je voulais juste dessiner mon plan à l'arrière. La base sur laquel je prévoie l'aménagement et un setra S 215 RL de transport scolaire et n'a de toute façon pas de siège à coté du chauffeur, hélas, je verrais si je peux en ajouter un, mais plus tard...

Bonjour,

merci pour ta reponse gasmobil, j'ai jamais eu de camping car alors je me pose beaucoup de questions sur ce point...

si je me trompe pas, t'as un bus pas tres haut, quel va etre l'ecart de hauteur entre la cuve et le WC ?? t'as prevu une valve anti retour (est ce que ca ce vend ca ?) pour pas que ca ressorte quand t'es dans une cote ?

et avec ca, le plan pour ce debarrasser des eaux noires c'est quoi ?? est ce que tu va devoir nettoyer ta cuve a eaux noires de temps a autres ??

a+seb
don't worry, be hippie !
GA Gasmobil Regular ·
pas de clapet anti retour. Même dans les WC à cassette classiques il n'y a pas de pb alors qu'on est literalement assis sur la cuve de 17 litres d'origine. Je met mon reservoir à eau noire dans ma soute, donc encore plus bas que le plancher alors pour un retour ... Cela dit, dans les SANIMARIN 35 il y a quant même un clapet anti retour, je précise que comme son nom l'indique, c'est prévu à l'origine pour les bateaux. Pour la vidange, je prévoie tout simplement une pompe et un tuyau annelé de 40 à dérouler pour atteindre le regard de vidange. En effet pas toujours possible avec un car de se pmettre sur une aire prévue pour les camping cars. Le car que je devrais avoir fera environ 3.20m de haut et avec des soutes de 60 cm de haut environ aussi. J'en saurais + mercredi, je vais le voir et l'essayer à Paris.

Comme vous disiez que il faut des materiaux classé au feu comment puis-je avoir le texte qui parle de ça? pareil pour tous ce qui est electrique je trouve ça ou? voila franchment pour le moment ça a pas l'air bien sorcier leur norme afnor moi qui croyait me taper 50pages de blabla interminable et imcomprehensible pour le neophyte que je suis alors qu'en faite ya 16pages et tout est bien expliquer. ça rassure autant que ça me fout les boules car il est ou le piege???

Hi everyone,

I'm brand new to the forum (I've been following along for a while now and I've read and printed all 51 pages!). I'm about to embark on this adventure and I'm leaning toward either a Setra S309HD or a Renault Carrier JN1E124 – buses that are 8–10m long max (and yes, I want to use it very frequently for weekends and vacations, both summer and winter).

For the Renault Carrier, apparently there's no issue getting manufacturer authorization for deregistration, but what about the Setra?

As for the rear door – can you move them further forward or block them and open another door somewhere in the middle of the bus instead?

Those are my first questions, because depending on your answers my whole interior layout will change completely.

Thanks everyone.

Fred91
GA Gasmobil Regular ·
Hello and welcome. At Setra, no problem for 85 euros ex. VAT, you have the authorization. In my case, they authorized the removal of the rear door and even a lowering of the floor in the cargo holds. Contact Arnaud DEBAIR at EVOBUS in the homologation department, 01 39 92 62 00.

SH Shanko ·
Hi patrick26, in a response you posted (page 46 or 47 I think) you mentioned that you don't need the manufacturer's authorization to convert a bus into a motorhome. But actually, you absolutely must request authorization from the manufacturer—it's MANDATORY. The guy from the DRIRE specified in the letter he sent me that for 'bus' bases it's often very difficult to obtain. I just wanted other people who read that response to know the real situation, at least according to the Mayenne DRIRE.
PA Patrick26 Veteran ·
Let's be clear!

How can a manufacturer give you permission to convert your bus into a motorhome without knowing what conversions you're going to make?

They don't give permission blindly!

What a manufacturer can give you is permission to carry out specific bodywork modifications, or changes to a door or staircase, or glazing work, or roof hatches. Full stop. That's where it stops!

No reputable certification service will send you a letter saying it authorizes you to convert one of their coaches into a motorhome while leaving the door wide open for anything and everything in terms of fitouts!

The mines engineer can ask you for manufacturer authorization for all bodywork modifications. If the manufacturer has chosen not to issue one, no problem—you go see an industrial coach-builder who is registered in the trades register as a coach-builder-constructor, you have them do the work, they put a nameplate next to the original manufacturer's, and you go to the mines office with the coach-building certificate they'll give you.

If the manufacturer gives you authorization, the additional nameplate will be in your name! That's the only difference.

Don't forget we put our vehicles through RTI (single-vehicle type approval). We're not Gruau or Durrisotti transforming vehicles in production!

And as the law states (an excerpt!):

For a vehicle that has not been bodied by the manufacturer or a coach-builder-constructor registered under no. 3115 of the principal activity code (APE) or 34.2 of the NAF code, and for which the following points are modified, a special authorization from its manufacturer must be attached to the coach-building certificate: the laden weights on the axles do not comply with the minimum or maximum ground loads provided by the manufacturer; the width of the bodied vehicle exceeds that provided in the descriptive notice of the chassis-cabin type; the bodied vehicle is a specialized vehicle not intended for the transport of goods other than household waste containers; the vehicle is registered under a dual category and/or dual body type; the coach-builder-constructor or the manufacturer has modified the chassis or chassis-cabin during the vehicle bodying.

However, the provisions provided for in the first paragraph of article 9 are only applied in cases where the modifications made to the chassis do not allow the vehicle's identity to be preserved.

Unless you bought a bare chassis and you're building the bodywork yourself, the guy at the mines office doesn't need to ask you for manufacturer authorization for glazing work as long as the vehicle keeps its original width! (At most for drilling a large rear door, if your vehicle is on a lattice frame). That's it!

STOP LISTENING TO THEM! Soon they'll have you doing crash tests!

I thus confirm that in the Mayenne, the DRIRE guy is giving bad advice, unless you both misunderstood each other....

PATRICK26 who stands by this😉
PA Patrick26 Veteran ·
SO I'M SAYING IT AGAIN!

You only bother the manufacturer's homologation service if you're planning major modifications!

If you're not touching the vehicle structure, you go to Veritas and the mines office.

If you have a chassis-cab bus, you can proceed and make small modifications to the bodywork (without touching the roll cages) and go to Veritas and the mines office without bothering the manufacturer.

If you have a lattice-frame bus and you want to do bodywork modifications, you contact the brand or a body shop. (If you're having the sheet metal work done by a body shop, don't bother the manufacturer—the body shop's stamp on the bottom of their body certificate will be enough for the mines office).

So you only bother the manufacturer if you have a chassis-cab bus and need to touch the roll cages while doing the work yourself, or if you have a lattice-frame bus and want to do the sheet metal work yourself.

Assess your skills before bothering the manufacturers, who will get fed up and stop answering anyone. Only submit applications when you're sure! (Once the bus is bought, the plans are finalized, and you're certain you'll be doing the work!)

So know that getting this authorization will never prevent you from wanting a camper in a bus! Stop stressing about it!

For my bus, the DRIRE asked me for the manufacturer's authorization! It was for the rear opening: 1.82m X 1.78m! 🤪 They wanted to make sure Heuliez's design office hadn't used the rear face to reinforce the structure (which makes sense...)

PATRICK26
PA Patrick26 Veteran ·
And for FRED91, the 3rd post on this same topic 🤪

The manufacturer doesn't handle vehicle reclassification!

What gasmobil is saying is that for 85 euros, the manufacturer looked into whether they could seal (weld, plate over) the rear door and cut out part of the steel bars that form the staircase steps on that door so he can install his shower there instead (for more headroom).

The day he takes his vehicle to the mines authority (after going through Veritas) it'll still be registered as a bus! Setra won't reclassify it!

The mines engineer, with Setra's authorization for the modifications, won't give him any trouble about the shower installation—and it's the mines engineer who will reclassify the bus as a camper truck!

If your bus doesn't need any structural changes, don't bother them for no reason!

You can certainly ask them about moving or sealing a door, and I think they'll respond. But that's not the same as reclassifying a vehicle!

Vehicle reclassification (changing it from bus to camper)—only the mines authority can do that! And the original manufacturer doesn't get involved! (unless.... read the post above!)

PATRICK26 There we go, I hope I've explained everything to everyone.... I'm off to bed. Good night kisses to you all....
FR Fred91 ·
Thanks for the information. I misspoke about the reclassification—I was thinking about the TCP to PL classification where I thought you'd need manufacturer's authorization, but with a motorhome I now understand it happens during the DRIRE inspection. Thanks also to Gasmobil for the Setra contact!

Hi Patrick,

Sorry to stir things up, but you don't have it all right:

In Mayenne, it's the same as in Sarthe and plenty of other departments, and it's becoming more common - the DRIREs cover themselves by asking for manufacturer authorization in certificate form to allow downclassification of the commercial vehicle (PL - just to be clear) to VASP.

BUT - and you're absolutely right about this - the manufacturer won't authorize a "home-car" downclassification, only a type/category change to "VASP". Heuliez makes this clear (I can't post the certificate online - it has the manager's name and signature on it): "furthermore, we specify that this vehicle must undergo supplementary type approval by the relevant Mines department, which will determine its new CLASS and BODY TYPE."

I can't attach (it's too large and won't display properly) the CRR14-01 form p4/4 from the DRIRE file with the manufacturer's reclassification authorization request handwritten at the bottom.

If you don't have that in Sarthe and Mayenne and other departments - according to Heuliez, which handles these regularly - well, maybe you could get away with it anyway by arguing with the engineer, but I wouldn't recommend it, even though we both know for a fact it's just red tape, especially since Heuliez provides the certificate for free.

Personally, I went with the simplest option.

😉Hey everyone, So I'm finally doing the paperwork for the bus this weekend, but I can only pick it up on November 10th. It's a vehicle that hasn't been driven for less than a year except for moving it around at the company. It'll be put on a lift for lubrication points and an inspection. Quick question: I'm not doing any paperwork for the inspection or mining registry even though my tachograph plate expired a year ago???🤪

Nice beast gasmobil😎.

So we agree then!

It's all the zeal of those engineers!

This document is useless!

Some manufacturers go along with it out of courtesy, others refuse, and they're right!

These bad habits picked up by engineers spread, and over time become standard practice!

Let's go back to what the law actually says and stop pestering the manufacturers' certification departments for no reason. One day soon, none of them will be willing to waste time on trivial details, and we'll lose access to this magic key in cases where it's really valuable (for major mods like slide-outs or rear doors for loading cars).

😏Hi everyone, I showed up back in September but I wasn't able to log back in🙁!

I just bought the Mercedes 303 I had my eye on, and I removed the seats (which I'm not sure what to do with) yesterday. I still need to deal with the rust, but then I don't know where to start (I've already done the plans, very important!!). It seems to me I need to do the electrical first, can you confirm that for me?

PATRICK26: I read that you advise against the 303 because of the curved windows, but why not remake them in fiberglass instead? (It works for all buses) It's lighter and I think it can look clean.

I'm lost in the AFNOR guides, is the one I need to order really "fitting out a vehicle as a motorhome"?

I didn't think there were so many crazy people buying a bus, that's amazing. Around me lots of people are being discouraging, yet they're not afraid to build or renovate a house!!! Maybe they're the crazy ones!!

AFNOR guide, mine's called: Motorhome Conversion Guide. so what you found should be good?

for the crazy ones: people are scared of what they don't know! for now we don't submit houses to DRIRE either, although normally you'd need electrical work validated by a qualified professional, and you absolutely must go through an architect for anything over 170m² of living space for me, I've been doing renovation for 16 years... takes me a while for a motorhome (it's smaller too 😉)

fiber, from having done it, there's a lot of work 🤪 unless all the windows are the same.

As promised, great news!

seb (sorry, sjunior) did a fantastic job and really helped me out!

We've got a blog!

It's not meant to replace this discussion forum;

however, comments have been disabled.

But on this blog, you'll find: organized by categories, a real treasure trove of information (standards, plans, diagrams, photos from meetups)

themes (electricity, water, heating)

I also took the chance to put together a history of my bus work (not finished, far from it!)

To access this database, just head to this address:

http://motorhome.blogs-de-voyage.fr/

ATTENTION! We haven't had time to get everything online! FOR NOW IT'S JUST A NICE PREVIEW!

If you have documents to share, don't hesitate to send them to me or let me know.

As you browse through this blog, you'll notice it has a real advantage over many others. Let me explain:

When I write an entry in my bus history and that entry involves electricity, I can link it to the "electricity" theme so it shows up there too. Magic!

We're thinking with seb (sorry, sjunior) about the possibility of other members who have buses under renovation or completed joining us to enrich this database.

Anyway, come visit and contact me. I welcome all feedback!

But I operate on the principle that if you critique negatively, you should offer a better solution than what's proposed!
