Oh yeah, I poured my frame rails full of molten copper. I hooked the negative on the battery to the frame core with 2x4 copper buss bar and then mounted the engine with a solid copper motor plate. The body mounting fasteners and bushings are solid copper as well. Not only do I have a better ground bus than both of you , I lowered my center of gravity as well. The scrap value on this thing is huge! Who needs insurance!
