We have the 26rs also and just returned to South Florida from Tulsa, Oklahoma. We drove lots of backroads and going 55 to 60 and averaged 9 mpg. We bought it in April of 2016 and love it...we had a 24 ft Itasca Navion prior and loved the mileage but hated making the bed each nite. Did you discover how to use the speakers over the bed?
