Hi there,
I can’t give you any info on the route via Makopong, but if you’re heading from Jo’burg to Mabuasehube, I’ve gone through the Skilpadshek border post (Lobatse) three times, then headed toward Sekoma, dropped down a bit toward Khakhea, and left the paved road to take the "Cut Line."
There isn’t much sand.
I don’t know what the conditions are like in November, but in May, June, and August, it was driving really well.
Hardly anyone goes that way, and we even camped without seeing any vehicles pass by.
One time we drove a bit at night and had multiple encounters (jackals, badgers, antelopes, not to mention guinea fowl, owls, etc.).
Check out the route I mapped on Wikiloc:
