I've pulled a 4 horse trailer (loaded) from Colorado to Virginia and back, loaded up another adult and two children, plus a dog and had plenty of room left over. This is the best truck I've ever owned and will never have anything but a Tundra as a work truck ever again. It has comfort and performance. After 4 years, it still burns rubber if I have to get going quick. The TRD is great. I love it.
Towing ability, TRD package, comfort and performance
If we could ever get good mileage out of any V-8 truck it would be the greatest improvement of all time!
