My Class C was a lot smaller and lighter than your 24F, and I normally only got around 8 MPG on the Interstates doing 70 MPH, so your numbers seem about right to me also.
With your motorhome being 5 inches wider, taller (many new units like yours now have 84-inch headroom), heavier and also geared lower (most now have 4.56 versus 4.10), it’s not likely you’re going to do a lot better unless you slow down.
I averaged 8.6 ~ 8.7 MPG over a 5,000-mile trip driving a 30-ft Class C of similar dimensions as yours, but had to keep the speed between 60 and 65 MPH. At the beginning of trip I started out at 70 MPH and the first tank of fuel was under 7 MPG. Slowest speeds where through scenic mountain roads and it resulted in best fuel economy.
