the strength of tubing is in that its a tube, not just in the wall thickness. by the same degree, the strength of a frame is in its ladder design, not in the wall thickness. frames need to have "give", if they dont, they will break at the weakest joint. Even big truck frames, I should say ESPECIALLY big truck frames, are built to allow for torsional twist for energy transfer. Anyone remember the ford commercial where they deflected the truck frame 8 inches or so on one corner? The only thing you gain with a heavy frame is a low center of gravity.
and you will really regret trying to weld that 1/4 to the 1/16th thick original frame, because if the weld gets hot enough to penetrate the 1/4 you are USUALLY blasting clean through the 1/16th.
