We are looking at purchasing a class c in the 2000 to 2005 age range. I have noticed that the class c's in California have been smog tested. Do class c's there have different emission equipment than other states? If so, do they get poorer fuel mileage because of their emission equipment. Is there any reason I should not consider buying a used class c firm California? Thank you for your feed back.

I live in California and have had a number of MH, vans and pickups towing trailers with California smog equipment. Based on what I read in these and other RV forums the miles per gallon are similar to what RV'ers report nationwide with the same vehicles.

We have all kinds of special rules regarding motor vehicles in California sanctioned by the Feds. Our vehicles are supposed to be cleaner.

There are several states that have adopted CA emission standards without damaging the mpg. I don't think you'll have any problem.

As long as the motor has fuel injection and not a carb, it's all good. Most likely the only differences might be temperature sensors that meter things like when the EGR valve opens or closes. And since there are several programmers for the ECM/ECU for FI motors, it's not hard to remap the thing and have what ever you want in performance; towing, fuel economy, power, etc.

Only reason to avoid buying in California is paying California sales tax, but that can be avoided by doing out-of-state delivery. And yes, even if your home state also collects sales tax, CA wants their cut too.
