Toyota trucks in general have never been known for fuel economy.
Ive had an '89, '97, '01, and a'05 Tacoma and they were all V6s and all got poor mileage. Usually 17-18 around town if i recall.
Im not sure how big of a guy you are but if saving a few $$ on fuel isnt a major concern, Id go with the Tundra hands down.
Theyre both reliable and have the best resale value of any truck on the market.
Either one is a good choice.
If they made a 1 ton with a diesel motor Id own it.
