2010 Toyota Tundra Double Cab Tundra Grade 4dr Double Cab 4WD SB (4.6L 8cyl 6A)
Great Truck
 I traded my 09 Silverado on this truck because of numerous problems and trips to the dealer.  I have had other toyota trucks over the years and returned because of the build quality.  This truck is smooth, quiet, powerful and bone solid reliable.  30% of the time I am towing a 5800 lb travel trailer and am very impressed with the 4.6 engine's towing ability.  In my opinion the engine is good compromise between economy and power.  Currently I am getting about 17 in combined driving, 19 highway and 10 - 11 towing.  I also like how the 6 speed transmission operates, the heating cooling system and seat fabric.  Biggest complaint is a rather flimsy bed, which I plan to cure with a spray in liner.
