Currently looking to buy another truck, around the first of the year. Just sold my '02 Avalanche to my stepson. The Avalanche towed very well with the 5.3L V8. Its was rated at 285HP. The 4.6L engines are rated at 310HP. Am I correct in assuming the 4.6 won't have a problem hauling a 2 place enclosed snowmobile trailer? Don't know a lot about Toyotas, never owned one before. Fuel mileage on the Avalanche was around 14-15 combined. Any info about the Tundras would be appreciated.
