As with so many things concerning these tough little UHaul trailers, the key word in the History is "supposedly." They seem to be related (Burros and UHauls) but the path is a bit fuzzy at times. Anyway, they are of a similar family since they are put together in two side pieces rather than top and bottom. Having owned both brands, they are very similar and great to own! Our primary historian, Ray Horner, has not been seen or heard from in several years, so many of us still have a lot of questions.
