kirbymurphy,
I am sure that either one will serve you well. Todays engines are light years ahead of the older models. I went with the Chevy because I wanted a smaller RV and the leg room and quieter ride were important to me. I think generally I get about 10% better mileage than the Ford but my engine is 10% smaller and the Chevy has a 6 speed tranny vs the Ford 5 speed. On the other hand the new Ford has an 8000 lb tow vs the Chevy 5000 lb and when crawling under both the Ford has a beefier frame. I originally went in to buy the Ford because of the frame and tow rating but after the test drive in both I went with the Chevy. It really comes down to personal preference and how sensitive you are. If my plan had been to drive 400 or 500 miles to a resort and camp for a few weeks and come home I would have gone Ford but my plan was to drive the hell out of it across the country hitting as many National Parks as I could find. In the last 6 mos I have hit 15 parks and 11,500 miles so the driver seat noise and ride comfort became paramount.
Just an aside my avg mileage for the whole 11,500 has been 10.8 mpg calculated not the meter reading. SD and KS killed the avg with 30 mph cross winds the avg there was only 9.1 but through New England and the Rockies it was a solid 11.3 and most of the central US was in the 12's.
