@Bill - curious how you got to that number. Here is my math. @65mph my Class C is getting 8MPG. That equates to 8.125 Gallons Per Hour My genset burns 0.2 GPH no load, 0.5gph half load and call it 1gph full load. I'll give it the benefit of the doubt and say 0.3 gph with an intermittent cycling heat pump Total fuel burn - 8.425 Gallons Per Hour 65 Miles Per Hour / 8.425 Gallons Per hour = 7.7 Miles Per gallon (effective) So 0.3 MPG hit. Maybe your decimal place got mis-placed ...
