As far as interior room goes I would recommend the first gen Tundra double cab as well. The '05 pictured belongs to my Sister. Her and her husband picked it up about 10months ago to be their family truckster, they tired of not having enough room in his Malibu or her HHR. My sister is about 5'10", her husband is about 6'2", the Nephews are 6'3" and 5'8", and all four of them fit comfortably in it, even with 2 small dogs. They came out from NM last X-mas(1200 miles) driving straight through and no one wanted to kill each other when they arrived. IIRC, my Brother-in-law said he averaged about 17-18mpg's, not the 30+ his 2010 Malibu did when they came out before, but he said the comfort/extra room of the truck was worth the 12mpg less.
