Within the EU a campervan can mostly park anywhere for a few days undisturbed same as any other vehicle. You living inside it makes no difference. If you tried parking anywhere and then living in a caravan that officially is camping and is not allowed as widely by a large margin. Not sure why.I would love to travel through Asia and Africa. The reason I asked the question is that it seems like towing a caravan gives you much more living space for your $$ than an integrated overland camper, as we're calling them now. Plus I don't have $400K+ for one of those, and I don't want a camper van. That leaves a caravan like a Bruder EXP-6 or nice tent trailer like a Patriot X3. I'm fine with towing and the limitations that come with it. So for me, the main downside of a caravan is the lack of a pass-through.
French Aires are specifically for campervans to stay on for longer, but "camping" with chairs, awning, bbq is not allowed outside that campervan, caravans not allowed (not always totally enforced though). You, your vehicle, one parking space that's it.
I wonder how many other countries behave like that?
I think I would rather take a sub 10 ton camper down a narrow lane than a long trailer, neither with a crawl thru?
