The Tundra is one of the toughest trucks out there. I use mine to pull a three horse trailor even over hills and it doesn't buck, lug down or anything. It pulls like a dream and comfortable, like riding in a car. I alrerady have 53,000 on mine and never had any work done outside of oil changes and rotating tires. These are very good trucks, wonderful gas mileage and I just cannot say enough good. So go get one today. The new ones are even better if that is possable.
