I have an 07 Double Cab Limited with the 5.7 that has been good to me. I tow a boat with it mostly which it does without the slightest problem. I had one issue with the front differential which was taken care of under warranty, other than that no complaints. Since I ride the motorcycle most of the time it only has 35k on it in 5 years.
I notice Toyota is really dealing on leftover Tundra’s.
