The ‘rents used to have folding camper, but have now traded that (and the car) in for motorhome type thing (Fiat Ducato based iirc).
Judging from the blog of their travels, they now tend to park up, and get the bus in to the nearby town (free in UK with bus pass, and not very much cost in most of Europe), or walk. And apparently it’s not all that much faff to make everything secure for driving, and for them, probably easier to drive on the autobahn than towing when in a RHD vehicle.
Personally, I’ll stick with a tent. Was quite pleasant camping in 2 force 11 gales, and snow 🙂
