Very cool man! Moving along!
I'll inject my uninvited opinion here:
1. Tongue weight does help tracking a lot. Good call.
2. The flipped axle makes since, but all that weight on those u-bolts gives me a nervous tick You're going to the trouble to have beefy tires and a beefy frame, and it's all connected by what looks to be grade 3, 1/4" u-bolts (assuming they are stock?). I imagine an unnoticed 6" deep I-95 pothole at 70mph and that's a lot of sudden force. I don't have a perfect solution, but will offer these ideas:
a. Get some really good, uprated bolts from McMaster Carr.
b. Distribute the load on the nuts (ha) and bottom plate as much as possible (wide grade 5 or 8 washers), and
c. Consider a safety strap made of 3/8" or 1/4" stainless cable that wraps "diagonal" around the axle and the spring. (stainless so you never have to touch it again). Fasten the ends together with the proper hardware, and then ziptie the slack down to the axle so it doesn't bounce around. Should something ever fail, the zip ties will snap and the strap will hold things together long enough to come to a safe stop.
You know me though, and you know I overbuild stuff. Just a suggestion if it's helpful.
