You have a point Tony... but in reality you don't ! LOL Neither does Lund in their propaganda. Airplanes aren't welded because their skin thicknesses are generally too thin to do so. Welding all the ribs/skins/reinforcements vs riveting would also make them heavier than riveting (eating into their useful load). That said the riveting of airplanes does prove you can make a stronger unit with lighter materials, than you can welding and why I stated to not compare a heavy stanley with a lighter riveted hull. The welded Stanley is definitely a stronger, more abuse taking hull... but it's also thicker and heavier.
