I have a couple of single wheel tent campers.I thought I would tow one behind an old car,(we used to tow it with a 36 HP VW) They are 1953 Heilite aluminum campers.The canvas is still intact in one,but is fragile.It was still in use by a friend until about 10 years ago,his family outgrew it.The other one is missing the canvas,He used that one as a utility trailer until he bought a truck.I'm going to sell them,I am never going to sleep out again.I never saw them being any more unsafe than any other light trailer.You just back up like a regular car,just with an overhang.Mine are so old they were not equipped with signal lights.I do have two hitches for them.
