Hmm, couple things, is that plate all 1/4"? It sure does not look like it will bend. But, you certainly get a lot of structural strength from boxed stuff vs. plate, and so you can use way less steel thickness. Also, those are true sliders, they won't help protect the sides vs. the sliders that have tube extensions. these are like boat sides (not to be confused with the practice of boat siding I've heard of) in that they push off stuff they encounter, vs. the body having to do that work. Last, it looks like it will accumulate mud and road salts up under there? How exactly are those attached?
