2008 Toyota Tundra Regular Cab Tundra Grade 2dr Regular Cab SB (4.0L 6cyl 5A)
Should have had a V8
 I had the V8 in a 05 Tundra and got better mileage than this one with a 6 cyl but it has the power. If you get the V8 you will get 2 or 3 mpg better at least. I think I will wait for the hybrid when I get a new one. I really love this truck and the reg cab looks tougher than the dbl or crew
