Odd payload numbers on the 2017 F350 DRW vs. 2016 F350 DRW

My opinion is and its only that, the extra payload is to carry the extra ugly. Looks like the 'tuner' crowd designed a retro 80's. Has to be the ugliest Ford Ive ever seen.

But wonder if that is the reason for the added extra & sharp creases in the body panels- stiffening the aluminum? The u-shaped 'eyebrows' just icing on the cake.

I am really curious though how the aluminum box holds up to weight and flex long term. Seems I read insurance rates are also going to reflect the Aluminum body. All for a few hunderd pounds
