I own a 96 T-100 x-tra cab, and an 04 Tundra 4 door, both 2wd. I recently looked at trading in the Tundra for an 06 access cab, wanted to downsize, but after seeing, and using a shoe horn to fit my 16 year old kid in the back of the access cab, I decided to stay with the 4 door. Also, there is more room in the x-tra cab of my T-100 than in the access cab in my opinion, and in my sons opinion.
