Questions about selling a French van in South America

Hi everyone, I recently arrived in Uruguay and I'm currently thinking about the best solution for my South America travel project. I have a 2013 Fiat Ducato camper van that's currently in France. My initial plan was to have it shipped to Uruguay so I could travel across South America for about a year, then sell it here at the end of the trip. But now that I'm here, I have a lot of questions about selling a French-registered vehicle in South America, particularly in Uruguay. So, I'd love to hear from anyone who's been in this situation before:

Is it possible to sell a French-registered vehicle in Uruguay without permanently importing it? Is it common to sell your vehicle to other travelers (French, Europeans, or others) who want to continue traveling with it? Are these kinds of transactions relatively straightforward? What administrative procedures should I expect? What are the risks for the seller and the buyer? Are there any South American countries where this kind of sale is easier than in Uruguay? Based on your experience, would it be wiser to sell my van in France and buy a vehicle locally to travel with?

Any advice, experiences, or recommendations are welcome. Thanks in advance for your help !
