The trip from Westminster to MD the camper averaged 12.7 mpg. This was 4 adults and their luggage. The average high speed was 65 mph
Today's travels I only have one fill up in lower VA and paid $3.149 per gallon and got 13.6 mpg. I then noticed when I stopped today that I had the heat on bi-level and this includes running the A/C so with that off it may help. Of course this leg of the trip there are only two of us so I am sure that this helped the milage too. On the negative side the speed limit was mostly 70 mph today and this didn't help the milage.
If anyone has questions let me know.
