Does fuel mileage in these beasts really matter? Asking for a friend. :B.
Really, you bought the coach, you're going to use it. Budget 8 mpg and hit the road. My opinion is it really doesn't matter what mileage I get as long as I get there. If that is important to you then looking for price per gallon is more important. The Gas Buddy app might become your new BFF. If you pay 5 cents more per gallon and get 2 miles more per gallon than "Fred" then the actual cost of your trip will be more so fuel mileage doesn't matter. The way you drive your rig, the weather, wind etc. will have a dramatic effect on your mileage anyway. I get better mileage through Florida than I do climbing the Rockies to Denver. Best of luck....Dennis
