Searching for dimensions

[toasty]

I'm doing some research before going to the dealer to do some test driving. I'm going to be replacing my 03 Suburban, and I'm toying with the idea of a crew cab truck instead of the Suburban. One of the main reasons for the suburban is our 2 85lb German Shepherds - they get the back cargo area to themselves. In the crew cab, they'd be stuck with the floor in the back seat... anyone have a tape measure handy that could grab a dimension measurement for me? With driver seat in comfortable position, looking for measurement from back of rear seat at the floor to the back wall area of  the cab, with seat folded up ( I understand the seat will overhang a bit, that's OK) - not planning on the under seat storage either.... any help is greatly appreciated!
