I traded my 2005 Tundra for a 2008 Tundra so we could tow a travel trailer. We have the trailer, but have not had it on the road yet. However, careful recording of fuel consumption (not towing) reveals that we get nearly 18 MPG on the highway, and 17 around town, which is quite a bit better than the older Tundra. The new one has the 5.7 liter V8. Bring the trailer home over The Cascades, the truck had no problem maintaining speed up the steep grade to Government Camp on Mt. Hood, although we are restricted to 50 mph for the first 500 miles of towing. We're very satisfied with the truck.
Very comfortable interior, quiet, solid. Tow/haul feature on the automatic transmission.
