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.
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 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
I want to downsize to a 2000 25ft class c with a 7.4 liter chevy. Dose anyone have something like this and know the fuel economy? Thanks for any info.
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.
