The other issue with the VW is a lack of power, particularly when towing. The problem with A-class or C-class campers is they guzzle gas and are no fun to drive. Rigid truck-bed campers are a good compromise, but have limited space.
After much searching, I found a lightweight truck-back camper that works really well and fits a wide range a vehicles. It's made in Australia and like the trailer that I mentioned earlier in this thread, it folds open to a large room with a queen-size bed over the bed of the truck and you can add a room to it that doubles the size of living space. The main tent takes about five minutes to set up and the whole thing folds down to about 10-inches thick and has no noticable effect on my Ford Ranger's performance. You can check it out at

I've had all of these out on a sandy beach in 30 knots of wind and they held up perfectly. So far, it's the best compromise of weight, quick setup and space that I've been able to find.
