this is a pretty weak test in my opinion, those barrels full of water are dropped from a few inches. my guys at work drop structural steel in the beds of our fords from over the bed sides all day long and the beds hold up fine. I would've never thought a bed would flex so much from a cinder block hitting it but I guess its all about talk and fit over function. that bed wont hold up to anything in my opinion. id like to see it flex offroad, that could be a good or bad thing. I really do like the cut outs for dirt bike tires and the speakers and stuff, the multi function tailgate though is still ridiculous. stay pretty gmc.
