speaking of storage box, were getting a U-haul next week but i use a mobility scooter, do you think the bumper would hold a mobility rack & scooter?
I've only seen one U-Haul "in person", so I'm no expert, but their frames have come up in discussion here a number of times, and I'll offer a couple of points to consider.
My 17' Boler has straight frame rails of 2"x4" box-section steel which continue right to the rear bumper, so a platform installed there would be directly supported by the frame. In contrast, the U-Haul
bumper (like the round-tube loops that are visible at the front corners) is an additional structure, which reaches forward and ties into the main frame rails. While it looks very suitable (to me) for its intended purpose of protecting the trailer body, I don't think it was ever intended to support substantial weight.
A bigger concern is likely the
distribution of mass. I don't know how heavy this particular scooter might be, but with platform it will be a significant part of the trailer weight, and being located way out at the back would make a major difference to the distribution of load (weight) between the axle and hitch, and to the dynamic behaviour of the trailer. While people often add storage boxes to the back of trailers, on such a small trailer (especially a 13' U-Haul, but even the bigger ones) I think it is very likely too much.
Another possibility is in the
front. Many owners have extended the tongues of their trailers (usually other brands) to accommodate additional storage. This has serious implications as well, but if the tow vehicle can handle increased hitch weight, it might be a better solution. In the U-Haul, the bolt-on tongue is a unique opportunity to make an all-new tongue with scooter rack, designed for the load.
