Wouldn't do either, U bolts aren't strong I would weld a bracket on the side of the chassis not on the flange, never weld on the flange. Then weld another bracket and bolt the two together or you can weld one bracket on the box and bolt it to the chassis going through the side not the top flange of the chassis/channel iron frame. Welding it solid will make the welds pop as tension has to be released somewhere when it flexes. Had an F450 previous owner welded the flatbed to the truck, that didn't last long, popped the weld several times till I could bolt it down. Use grade 8 fine thread a 5/8 bolt or bigger is best and put a board, HDPE plastic shim or something between the box and the frame thin as possible to prevent squeaking of metal to metal.
