When Limey said "easily pulled by a small car", it reminded me of this photo. This is the camper that is now the flat-bed utility trailer, intact, and, in use, as you can see.
We pulled that trailer from south-central Kentucky to Denver with that Ford Tempo (4 cylinder/4 speed) in the pic. Went across the Rockies a couple times, too.
That car was a complete and total turd, in appearance, and performance. But it towed that camper admirably enough.
