Yes but we only want to AC part....we dont need much heat for the truck and we have one of those little box heaters that will run you out of the truck if you are not careful.

That's excellent! I did 7.1 mpg, fighting a bit of wind, at 79,900 lbs.

Was a lot lighter on the return trip, but I was surprised my fuel mileage didn't increase that much. Oh well.

Just put on new steer tires, they need to be broken in.
