This is my second Tundra, my first was a 2000 SR5 4x4 extra cab. The only reason I sold that one was for a bigger rear seat. It was a great truck, with good power and great reliablity. My new truck is even better, with the TRD package it ride great and handles the dirt and snow just fine. I have not towed anything with it yet, but forsee no problems. Although slightly smaller then the other full size trucks, it has plenty of room in the back and front seats.
Power rear window, push button 4x4, larger bed in the double cab. Quality, quality, quality.
Greater tow rating, long bed, better turning radius, and of course fuel economy
