I don't what all years this applies to but my Dodge is an '08 and it does apply. Dodge 3/4 and 1 tons are identical except for the springs. All the bearings, brakes, axles, etc. and interchangeable. My 3/4 has factory air bags and when they're aired up, it will hold a bunch of weight.

It also requires a ladder to get in the bed while the Tundra has a very low bed. That's something for the OP to consider. I added wheel to wheel nerf bars so I can get at stuff in the front of the bed. I'm 6' tall and the Dodge bed rails are too high to reach over. I also added one of these truck steps on the rear.
