I have had my Tundra for a month now and pulled a 23' camper "1970 model" so it was pretty heavy. I had no troubles, I had to go up and down a mountain. The brakes stop wonderfully. I pulled the mountain going around 45 mph no problem.
The engine is the best feature by far. I just has so much power. The seats are very comfortable and plenty of room.
Gas mileage around town, on the road is is pretty good. It is better than my 2000 model 4.7 litre. I would love to have the controls for the radio on the steering wheel. It does come with controls on steering and a JBL radio but is an expensive add on.
