I have a 23 RST CC 4X4, 6'7" bed, 3.0 (305 hp, 495torque). 8 275/60/20 BFGS. Only mods are a 2" front level and rear airbags for towing.
Bought the truck end of July, just hit 8000 miles....I am averaging around 22-23 in town on my work commute. Have averaged as high as 27-28 on the freeway. Even more impressive is I got 13.5-14.0 MPG pulling my 8500 pound travel trailer around Idaho hunting this fall. When I fill up, I have seen my tank as high as 650 miles to Empty. With the 10 speed transmission, its an impressive combo.
That is real impressive.
