Class A vs class C

If you are looking for which to buy based on mpg it still depends on where you live, how you drive, how much you travel with, and the daily weather. I just completed a 5700+ mile trip through 13 Western States and averaged 9.78 mpg with our Chateau Sport 26Q Class C with an 8.1 Vortec engine. Highest was 10.8 and lowest was 8.1. My goal was to average 9.5 and that's what I based my gas budget on so saved a couple of hundred dollars. I also don't pull a toad so that also will factor into information. So if you can get 6 to 10 then you are in the ballpark. I hope that helps.
