Well, so far I haven't seen any one say they're a structural steel engineer or something related to designing steel frames for trucks or MHs, or did I miss it someplace?
If one pops up, my question would be "how do they determine the weight capacity that they post"? My guess would be they assign a weight that is very, very safe/conservative because they have no idea what people are actually going to do with the hitch. It's the mfg or engineering firm that stands a lot more of a chance at being sued if one fails.

I saw a comic strip (Calvin and Hobbes, IIRC) where the kid asked his dad how they determined the weight capacity of a bridge. The dad answered that they build the bridge, then run heavier and heavier trucks across it until it breaks, then they rebuild it and assign the weight limit.
That makes as much sense as some of the stuff on here...
