MPG for transit based motorhomes

My current motorhome is a Dynamax Rev on a Promaster 3500 and gets 15 mpg. I'm hoping to get similar mileage.

That is decent fuel economy. Too bad that chassis is offered only with a SRW axle. A DRW would have done the chassis wonders.

Someone on the Phoenix Cruiser forum with a Phoenix TRX (2019 Transit chassis, non-EcoBoost gas engine) is reporting 11mpg, non-pampered cruising 65-72 mph, a negligible improvement from our 2007 E350 6.8L-V10 Phoenix Cruiser 2350 HERE, driving under the same conditions. We get a solid 10.5 mpg trip average, no towing, pampered 60-62mph.
