I have a 2011 Tundra that I have hauled an 8000 pound trailer A BUNCH with, and it's tighter right now than the 2014 Ford 350 was when I drove it off the dealers lot. It's very comfortable around town, and haven't put a nickel into it for repairs. When I say towed a bunch, I mean several thousands of miles, including one trip from Montana to souther Oregon, up through Washington, into Canada, up to the Yukon, across into Fairbanks and back home again.
Another trip was to Bella Coola, and if you want to see some scary road, go on U tube and look up "The Hill" on the road to Bella Coola from Watson Lake. It's steeper than hell, narrow and dirt, and the Toyota handled that like a champ. I probably would have been better off with a diesel, but that diesel didn't get much better mileage towing than the Tundra, and the $100 oil changes were aggravating.
