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...
You're getting better than I , but all my trips so far are under 1.20 hours. So combined with urban traffic. Just over 6 mpg with ours ( same rig as you). Not broken in yet. Under 800 miles on it. I travel around 65-68 mph. I suspect it'll go up. Yours too probably.
