Nice looking rig. What is your gear ratio? That makes a difference in MPG's apparently. I seem to average 9.6ish towing my 23LB with the '11 ECOscrew w/ 3.73 gears.
BTW -- If you figure out how to change out the gas tank to the 36 gallon - let us know. I can't imagine that it would be too problematic to change it out and that extra 10 gallons would get you down the road a bit further when towing!
