JollyJerry, I only get 15 MPG towing. But, as I have said before, I bought a Toyota not just for towing. I bought the Tundra as I believe (as does Consumer Reports) that the repair record far exceeds the other trucks on the market. While I do have to purchase more gas than some of the other trucks when I am towing, my repair bills will be lower. It's one of those "pay me now, or pay me later" kinds of deals.
