window opened
Is it alright to have a window opened by the sofa area when traveling down the road or dose your mileage drop??

I think that since your motorhome was never designed to be especially aerodynamically streamlined, and is creating significant amount of drag already, an open window is not going to make any type of noticeable difference in mpg.
I measured it the other day. 9 mpg with the window closed. 8.99999 with the window open. :B
