The engine does not make power where it's needed for towing. It belongs in a SUV.
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.
