ok guys I got a hold of a 40 ft mobile home frame. Before we have this argument on here it has the dexter axles and I have the replacement hubs to make it a standard 6 lug so lets not argue about that. As everyone knows the frame is fairly flimsy. I plan on cutting it back to about 30ft. just long enough for 2 zjs. What are my most beneficial options for bracing this baby. up. btw I will be converting to gooseneck.

I've always heard that welding a large diameter pipe down the center length of the trailer helps a lot with twisting.

Some triangulation and cross bracing wouldn't hurt,

Yea heard a bunch on the pipe and planned on doing it. What exactly you mean on the triangular bracing
