You won't have to wait too long. The new 07 Tundra is going to be offered in 5.6 V8 and 6.0 TD form.

Engine size is not the answer. The issue is the trucks frame and drive train (aka drive axles, differentials, suspensions etc)
Tundra is nothing but a beefier Tacoma with a V8 car engine. You can not compare a 3500 Dodge/Ford/Chevy Truck with an real 1 Ton Diff. in the rear(the size of a small engine) with that puny thing the almighty Tundra offers (that's a 4Runner rear axle).

Again call me when Toyota makes a truck that can move at 18,000 LBS GVW and tow in excess of 15,000 LBS at the same time.

The Tundra is "barley" a 1/2 ton truck. I'm talking at least a 1 ton duel rear wheel with 8' bed.

Plus V8 diesels are like little dogs, they make a lot of noise but have no power ... straight 6 diesels are the only option. Toyota's Hino and Nissan's UD trucks have nice inline 6 cyl. diesels.
