2007 Tundra Crew Max
 I purchased this truck to pull a 30 ft 7K lb trl.  It does it like a dream.  It will out pull my buddies Excursion with a 6.0 diesel, a 2500 dodge with a cummins and a 5.3 chevy pick up. All with shorter and lighter trailers. Here in PA we have quite a few big hills and it handles both sides great. The fuel economy is a little stiff.  If the fuel tank were larger this could help out.  Too many stops along a trip.  I used to have a 96 suburban with a 6.5 turbo diesel.  the only thing that was better on it than the new tundra is the size of the fuel tank (40 gal vrs 24.6),  I was able to go 5-8 hours of towing with one tank.  The new tundra needs to stop every 3-4 hours.
