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.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
