A question came up recently regarding gas mileage. As prices rise, I think this is an item of interest to us all; particularly those who are contemplating buying a new tow vehicle.
I think it would be of interest if we posted what our tow vehicle is: Year, make and model; it's engine size; fuel; transmission (if there's an option); whether it's 2WD or 4WD; the rear-end gear ratio; and the approximate weight of the towed load. Then, if you have it, the average highway mileage you get, your average combined city/highway mileage, and your average mileage towing.
Hopefully this will give us a pretty good picture, real-world, of what to expect from the various engine/tranmission/rear-end/towed weight combinations. The caveat here, of course, is that YOUR mileage may vary!
