To use our past week's experience for context, our westbound trip was a total of 254.8 miles from our driveway in Houston to Antler Oaks RV Lodge in Bandera. Our fuel consumption was a flat 10.0 MPG. Coming back home basically retracing our route our mileage was 252.7, and that yielded 9.1 MPG.
As a point of comparison I typically see 12+ miles to the US gallon towing our 2014 FE 192RBS with our 2005 5.3L V8 Chevy Avalanche. Worst case, I don't recall ever seeing anything under 10 mpg so even with a non-tow friendly 3.42 axle ratio it's never stressed, 'though I do always tow in 3rd with Tow / Haul engaged. A larger vehicle doesn't always mean worse fuel mileage returns. ;)
