I figured just as extra support I'd make a ladder type bracket to weld on the underside of the tub going from wheel well to wheel well if there is enough clearance. Just in case, I don't wanna have someone sitting in the back then all of a sudden the pan gives out. I know the gas tank is there, I meant any type of electrical wires or hoses. That's bad wording on my behalf
