My average calculates between 6 and 7 mpg towing the CJ-7. I try to drive 62 max on cruise, no tow haul mode on mine, the button is to defeat overdrive on the downhills to get engine braking. We have the 310 hp V-10, the newer ones are 362? hp with 3 valves per cylinder. Don't know how that affects the mileage. 33 ft class A.
