Tundra replaced a 1999 Suburban that was my work truck but just had too many reliability issues. The Tundra offered a configuration plus Toyota's reputation for reliability and durability. The Suburban was a great design and even as a work vehicle it was tough but just too many of the components died an early death. The Tundra is roomy, quite, powerful and came with a kicking stereo even though it is not a priority for me as this is a work truck. I've put about 1100 miles so far and the ride, though choppy on concrete segmented roads, has smoothed out and of course, is much better with a load in the bed.
Drive train, roomy cab actually can seat adults even on a trip.
The ride I think could use some tweaking. Not only can it be choppy but also it sometimes feels like the bed is jerking at the cab. This is the long bed double cab 2wd. Gauges are hard to read. Tail gate latch has problems and needed to be fixed due to a flimsy plastic clip aligner.
