The guy made a whole new frame for his mini truck. Lots of photos. The truck is a street rod, not a 4x4, but still interesting. I wonder about the legalities? I have a small amount of rot on my frame and was thinking of at least rebuilding the rear section.

What I find most interesting is the frame rails are box beams bent to shape. That means there is some shops out there where an amateur can get significant accurate bends done to steel tubing.
I know if you pack sand into a tube you can bend it much sharper without collapsing. Similar should be able to be done with box beams.
