Recommended Truck Tow Vehicles

The wife and I are considering buying a truck to add to our vehicle stable. A key consideration is of course using it as our TV instead of the Sienna. While the Sienna "works", I would prefer a more robust vehicle be assigned the duties.

We are leaning towards a V-8 Tundra 4x4 but would be interested in hearing what others think. We looked at Fords and Chevys but it seems like you get to 40K in a hurry if the websites are accurate whereas a similar Tundra looks to be 5K cheaper.

Any opinions out there?
