You are driving something like it now, you have basically the same drivetrain but maybe a little more frontal area. Most modern Cs are same oversize width, only 1/2 foot to a foot less height than small gas A.

Drive it the the same speeds you drive your Daybreak, you will probably get no more than 10% better mileage. Unless the C you are looking is atypical, a narrow body, or low-profile.

The universal answer for Class C gas mileage seems to be 7-10 mpg depending upon how you drive, mostly.

Drive faster and the wind resistance picks up considerably (I think it's a expodential rise) and gas mileage goes down fast, of course.

These things are almost like driving bricks, from an aerodynamic point of view.

I intend to use some "AirTabs" to help this a bit, but I don't really expect too much - enough to have them more than pay for themselves in a 6,000(+) mile trip, I hope.

Just came back from a 1000 mile venture with my 2003 25 footer, 350 chevy (EFI) and got an impressive 10MPG - From Michigan to Kentucky and back - some hills in KY as well. Was actually happy with the mileage

I had a 20 ft class C - it got about 8.5 mpg; I had a 34 ft. class A - it got about 8.5 mpg; now I have a 26 ft. class C - it gets about (you guessed it)....

The only way Is get a cummings on a dodge chassis. The ford Is not to good on fuel or gas.The Cummings six cy Is the only way to go.


Wife bought me another Motor Home I guess she was tired of me crying.

Your gas mileage will depend on how you drive your RV.The faster you drive the mileage will drop. Gasoline RV are harder then the diesel but the way you drive Is the secret on how to get the best mileage possible.On the Interstate you will get the worst because of the high speed. Stay 60 and under if possible and the mileage will be better I have found.It all up to you the way you drive your RV.

I have a 30.5" bumper to bumper. I gotten 9.3 average since new however the toad seems to knock this down to 8.7 average since I got that. Like the other posters I'll join the band wagon and agree Speed is a very big factor. Slow down and keep your wallet fat. Patter
