There are too many variables to give a credible answer - weight, engine size, transmission, rear axle gearing, tire size, etc. all have a major effect on fuel economy.  Which diesel, which gas engine, what chassis, and on and on and on...

Generally, though, I would exect the diesel to yield better mpg hauling heavy loads.  For that size Class C, a typical  gas chassis might be a Ford E350 or E450 with a V10 engine and I would anticipate around 7-8 mpg.  Maybe 9 on a good day.  A typical diesel chassis would be a Chevy 3500 Duromax or Dodge 3500 Cummins and either should produce 10-11 mpg, maybe even more in good circumstances.

RV Roamer thanks for the info
? ? The variable's would be standard E450 24ft superslide. We are looking at right now. It seems to have everything we need except diesel. It comes with a V10.
I personally want a diesel but its hard to find one in that size. Talking to the RV dealer he said he cant move them. Due to the noise it makes in the cab. To me thats just a diesel and you have to expect some noise.


Thanks for the info and keep it coming.
