"Translating" 10.2 Imperial MPG to US gallons gives a figure of about 8.5 MPG (US).
The good news is once you have 20,000 kilometers on your lovely NEW Rv mileage will improve by about 20%.

Kustom Koach Class C 28'5" 256 watts solar, 875 amp hours in two battery banks 12 volt batteries 2500 watt inverter.
On a 1998 /class C (26.5 Ft), no toad, 185,000 miles (yes, that many), always drove the speed limit until it reached 70 MPH, and measured every gallon in, got average 8.68 MPG Sold it in 2008 and bought another, same model. Now have 22,000 miles on the unit and mileage comes in all over the place. About half the tanks are now in the low 9's. In neither engine have hills changed mileage (and I live in Colorado). Good luck.
revdsid, I get 50 on my Prius and when I towed it on the dolly I figured with moho at 9 and Prius at 50 and greatest miles on Prius I was still averaging quite well and you are right, it ain't bad considering it is your house on wheels.
I have a 2004 Winnie 31C with just under 10,000 miles, I never tried going 55, I have a lead foot and since mu speed limit is 70 I usually do 75. At that rate I get the 7 mpg but once I hit the hills and passes here in Idaho it can drop down to 5 mpg.
Should have gone Diesel.
If we all ajusted our speed down a few miles per hour you'd be surprise at how many more miles we could get from just one tank full. I had other motorhomes of all sizes pass me on the road like I was sitting still and they only bit me to the same destination by 15 or 20 minutes. I got 12 mpg and they probably got 5 or maybe 7 mpg.
Slow down folks and enjoy the ride and you should be ready for any emergency. Happy motoring

Thanks to everyone for all of the input. Next spring, when we bring out the MH, I plan on putting synthetic oil in it. I will also try slowing down to the 55-60 range and see what happens with the mileage. (We were on time constraints for our 2600 mile trip, so we drove faster. We're looking forward to full retirement so we won't be in such a hurry!)
If that should happen to come up in Dutch there will be an English link you can press near the top right corner of the page. In the same corner is a search box where you can enter "boat tail" to get links to the available articles. One claims 15% rather than 7.5% gain but all are rather light on details.
Another possible (but this one is practical) fuel efficiency improvement device is the Airtab. It creates a virtual "boat tail" using small air vortexes (see the previous post).
I don't know the efficiency gain - it's fairly small, maybe 5%. There is no way to reliably measure this with only one vehicle.
I can say for sure it really does change the air flow, keeps the rear cap cleaner and lets me use my rear view camera even in the rain, which was previously impossible.
I put them on - for about $200, IIRC, and I have no idea if I got my money back in fuel savings or not.
