We've owned our TS since new and have averaged 8.8 mpg over those 109,000 miles. The average has even gone up .05 mpg over the last year or so. Our coach is 40'5" long with the Cummins ISL 400 engine and, with toad, currently weighs about 35,000#s. Until 2 years ago we towed an XTerra SUV which weighed 1,300#s more than our current toad. According to my Silverleaf, I have had a number days of over 10 mpg and even had one of 11.5 mpg over 250 miles a month ago.
A lot depends on how you drive; my cruise control is set at 62 mph and is almost always on, we are on highways or long open stretches of road for a lot of our travels and always try to drive downhill with a tailwind (well it worked on the day we got 11.5 ;D ). We broke in the engine very carefully, I drive like a raw egg is under my right foot (except when the cruise is on
), I constantly monitor my tire pressures and I follow the engine/chassis maintenance schedule very closely. It pays off at the fuel stops.
That said, and as others have commented, 1 mpg difference will make a difference in fuel costs of less than $1,000/year. Compared to the cost of the RV and your total operating costs, it is relatively insignificant.
