That was kinda my point. :lol:In those trims the trucks are very similar, but there are some major cosmetic changes done at the factory. By the time tires, rims, interior features, shocks, and other OE special features are added the trucks have changed production lines. Sound deadening is installed when the interiors are installed. The trucks only share a power train, frame, basic body, and basic interior features. Yes the interiors look the same, but they are not installed in the same production line for both brands.
