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 wondering?

What engine? 7.7 is pretty solid. You may pick up a few tenths as you learn how to drive it better and it breaks in. Are you using the "econ" mode?
You are going to hear from a dozen people with different coaches most will claim great mileage. The problem is if it isn't exactly the same as your coach it doesn't matter. There are just to many different variables. I would keep track as you want to know if something might be wrong dropping your mileage. I use Gasbuddy as a handy way to keep track.
One outher thing I run Power Service Diesel Kleen it cleans, improves Cetane and makes my engine run smoother and is recommended by Cummins.
