When it comes to comparing MPG, the first liar never has a chance.

i know some one who claimed 12 mpg with a older 460 ford in a 24ft class C, i get 8 to 10 in the hills and mountains with mine never had it on the flats but bet it might get as much as 12 mpg on some good flat roads,my PU got real good mileage when on the flats going to florida one year.

That's great. Are you using US or Imperial gallon in your mpg calculation?

Be leary of MPG figures as some will quote a 1 or 2 tank full reading. I have gotten as low as 8.8 MPG and as high as 17.8 MPG on individual tank fill-ups. Over 28,701 miles my average is 12.1 - I record my expenses. My RV weighs 9,020 miles when we leave home and is 22'-5" long.

Did you ask if 13 is up or down the hill? Mine isn't personal experience but I have friends (2) with chevy class C that claim 7 - 8 mpg. If milage is important to you, I think I'd go out for a ride and see for yourself.

What year? How long is your rig?
1982 and it's 23' long. This fantastic 9.5 mpg I got was driving at 55 mph on the highway. My overall average would be around 8 mpg.

That's about right, considering your 1982 has a carburetor.

I can understand the low 8.8. The high 17.8 seems like a human error ;-).
Anyway, 12.1 average is great.

9200# 19' Class C on a SRW 4x4 Silverado chassis, 8.1 & 6-spd Allison. On ~level terrain, 12.5 @ 65-70, 13.8 @ 55-60. But those numbers are from the dash computer, which has been slightly optimistic when checked against fill-ups. Partly due to the Onan's gas not being measured, I'm sure.
