The plan is to mount to all three axles actually and maybe even cross in the back and front to tie in the hitch in the rear and the winch up front. The PO had a pretty wimpy mount and I don't want to ruin the tub. Should be plenty strong. I come from a racing background and I'm fortunate to have access to lots of talent and machinery for free or for the cost of beer. It's nice having a waterjet machine at your disposal.
