I have always wondered about strapping a frame. I don't understand how this really helps much as compared to boxing the frame. Or even adding plates to an already boxed frame. I just don't see how adding a 12g strip of material and stitich welding it gives much strength to the frame. And it seems like the strap would hold dirt and moisture between the strap and the top of the frame and cause it to rust. Or do you run the weld beads the length of the strap so it is sealed? Even then the amount of strength added seems marginal. It just seems like boxing the frame adds much more support with about the same amount of work as strapping. Help my understand this my jeep buddies.
