I have a single axle utility Carson trailer with 2x10 plank floor and 16 inch sides ,
works great for VWs , 356s , little Fiats and stuff like that ,
plus you can attach plywood to the sides if you have to move "stuff"
its too narrow to take a Wide body 356 or wide body 911
if I was going to build another one I would put sockets for stake bed sides like on trucks ,
And yes having a utility trailer gets you a lot of requests to help people move !
PS , and when Bruce starts building trailers I would have him build me one too
