Just getting used to my new 2019 Fleetwood Discovery LXE 44H. 44 foot diesel pusher towing a Jeep Cherokee. I am averaging about 7.7 miles per gallon. I believe this is pretty normal but just wonderin...
Without knowing at what speed you cruise, hard to say if that is good. I did a 100 mile test at 45 MPH and got 10 MPG but did not want to take another day to get home from WY so back to 65 and 7.
