The tundra won't pull my boat in top gear. The best mileage have seen is 7.8 mpg. Combine that with about 22 usable gallons in the tank and I'm lucky to run 150 miles without stopping.
My f150 would get 11 mpg under the same circumstances and had 33 useable gallons.
Does your Tundra have the towing package, or the tow switch on the dash? The switch is supposed to alter the settings of the tranny to make it shift at different points and be more towing-friendly. I have not towed anything heavy with mine, a very light boat weighing less than 1000 pounds, and a utility trailer with perhaps 1500 pounds of stuff on it, so can't really comment.
