Yes I was VERY surprised to find out before I started this project that the little Cummins 6BTA outweighs the seemingly much larger 7.9L PSD by 120lbs. That's why I added 200lbs of spring capacity on the front springs. As for the frame folding one there will be NO jumping and two it's a SD not a Raptor. I think it'll take it. Right now I am doing the wiring and I must say it's not easy. Especially for someone like me who doesn't really understand electronics. I come from the old school where everything is mechanical. You can see fuel, pump parts, rockers, pistons and stuff but there is NO visual with electricity. Especially when it comes to computers. I'll get er done though.
