I've owned 2 TRD model Tundra's, one an 07 and the last was a 2015. Overall I thought they are pretty good trucks except in the gas mileage department especially when towing. My 2012 Ram 1500 5.7 with a 355 ratio rear towed as good if not better than the Tundra's and got better mileage all around. Neither gas 1/2 tons will come close to towing like a 3/4 or 1 ton with a diesel.
