2008 Toyota Tundra Double Cab SR5 4dr Double Cab 4WD LB (5.7L 8cyl 6A)
Pleased but not completely satisfied
 The truck has done everything I have wanted it to do. It has performed well off road, on the highway and in the snow. I have put it to work hauling and towing and it has not failed me. As discussed below,  Toyota put cheap tires on the truck. I shouldn't have to replace them at 25K. One of the tires had a crack in it. The local Firestone dealer told me that they tires were to light for the truck. If do your own general maintenance such as oil changes, you will hate Toyota. Changing the oil is time consuming and difficult. See below. I think the under-seat storage bin should be standard. I recommend it. The gas mileage has been as expected: 11-14 in town and 16-18 on the highway.
