The real information behind the pics is not in the pics themselves, but in the link which shows in depth measurements of the bed lengths, widths, depths, CA's, WB's, etc. It gives you a chance to compare the 900's to the 800's measurements side by side. BTW this is directly from GM's 2007 Trailering Guide.
The dimensions illustrated in the sketch are all the same 800/900.
The box is 50mm deeper and much stronger.
The rear flare at the back of the cab never made it out of the studio.
I'm suprized no one noticed the windshield rack angle change.
The question of a long box on a L/D Crew ........ aint gunna happen.
The fuel door still hings from the front.
"GM Oshawa's" assessment is his opinion.
Both the Chevy and GMC are distinctive and very nice!
(I like the GMC)
Oh ya.........The Titan is a piece of @#$%.
