I opted for a Winnebago with a Workhorse 8.1 engine. Pulling our CRV and fully loaded, I get about 8.5mpg. I've got plenty of power that has never been an issue. My wife has gotten used to me passing the big boys (ie, the DP's) on grades in the mountains. But, she still gets nervous when, at a stoplight, I open the window and ask the Corvette next to me if he wants to drag to the next light.
(OK, the last part was made up, but when that 8.1 downshifts and the tranny kicks in, I feel like I could give a Corvette a good run for its money!)
