I don't have pics, but I went to the dealership on tuesday and sat in the back seat of both.
I'm by no means a big guy (only 5'7) but I felt TINY in the back seat of the CrewMax. Almost like those basketball players on the Chevy Aveo Commercial.
What sold my wife to spring for the crewmax was sitting back there with a carseat installed. I don't know if you ever sat in the back of a truck with a carseat, but it is usually an unpleasant experience. She just imagined traveling to see family, and being able to sit back there with the baby and remain comfortable. Nothing in the market competes with the crewax as far as usable interior space.
