I personally had a 2004 Tundra crew cab. Loved everything about it other than the fuel mileage. 14 was the best...on a road trip to eastern Washington. Everyday driving would run right around 12-12.5(I hand-calculated every tank....literally. Everyone I talked to with the same vehicle (4 door) would be the same 12-14. Now the extra cabs would get 17-18......geared different?.....maybe. She ended up totaling it( took out a power pole 1/2 mile from home) and we ended up going with a dodge mega cab for its replacement. She still wants a 3rd row, and we started looking at the Nissan Armada (Toyota/Nissan.....Potato/Pototo). Upon further researching, if you like more luxery, the Infiniti QX56 is a mirror image of the Armada. That's what the wife is going to end up getting. Take all of what you read for what its worth. Test drive all. Good Luck
