Weight capacity for TT bumper

spare is in the pass thru

If you bolt the carrier around the frame attachment point, then the chances of it failing are very very low. Also the type of carrier makes a big difference. The short ones that put the tire a couple inches away and near center of the bumper are the best. Those that are hinged and sit the tire high are the ones not to use, they would stress the heck out of the bumper.

I had a few ideas on my way home from work (hour fifteen drive gives lots of thought time), and was thinking that a rack mounted on top of the bumper, close to the back wall would work to have a stable load to mount a generator back there as it wouldnt be leveraged out, so when I got home I measured my generator, then went back to the trailer and found, eh, wont work either, bumper is too close to the wall, the generator is 18" wide, so 2/3rds would overhang the bumper. Even though the mass would be low on the bumper, it would also be cantilevered out too much to be safe, so nixed that idea as well.

I also took another look at the attachment points. There are 1/8" angles welded to the frame and the bumper. They are well done, but as mentioned before, the wall thickness is too thin to support much weight. I was going to mount a truck box back there, even installed a bolt on receiver, but after looking everything over, decided not too, that and it would block the water heater outlet.

Bottom line, to brace the bumper to be strong enough to support overhanging leverage would add too much weight to the trailer, and a ton of work to make it strong. Not worth it.
