We've been getting crazy good mileage in our Tacoma, 107,000 on it now, 5 speed. Totally stock other than those frame plates you welded on Isaac. Running 22~23 MPG on the highway if I keep the speed reasonable. I expect when I put the camper on it will drop a little. It's running the stock 265/70R16 size in a street tire, too. Best I ever do in the old truck is 18ish most of the time and it's got no power at all. Be interesting to see how it does when the WilderNest comes off and some of the stuff gets moved over. I'm sure transferring 500 lbs from will drop the mileage in the Taco and increase it in the Hilux.
