2002 Holiday Rambler Imperial 38' 370 hp Cummins ISL. 7.9 according to the computer. I will actually calculate it by hand one day.......

2000 Newmar Mountain Aire 40' 350HP Cummins pulling a 14' enclosed utility trailer. Running mostly two lane highways that day at 60-65mph.

The only time I bothered to check my MPG it came out to 8.9mpg and I had been bucking a headwind for many miles that day....I was a bit surprised. The previous owner told me that the lowest he got with it was 8 and it sounds like he checked mpg all the time.

2005 40ft. Beaver, 34,000# fuel and water. Pulling Grand Cherokee, 5400#. 400hp Cat C-9. 5.5 to 8 mpg, depending on terrain and wind. 65 mph most of the time, sometimes 70.

Mileage is not a great when pushing an 8.5' X 12' wall along the highway. I averaged 7.3 over the last 19,xxx miles. Don't know about the next 19-20,xxx miles as i just replaced a broken exhaust manifold last summer.

2006 Thor Mandalay with the 400 hp Cummins ISL. 7.4 average mpg over 107,000 miles.

Trips with tailwinds = 8-9 mpg.

Trips with headwinds = 5-6 mpg.

Tow a Jeep Grand Cherokee about 70% of the time.

MPG has so many factors involved, every coach is different! And not two drivers drive the same! It is impossible to determine! Two different drivers in the same coach, will get different MPG #'s!
I used to tell people that ask me what the MPG were on my MH, "If you are worried about MPG, you should not get a MH!
All that said, me, being a retired O/O trucker, fuel was my biggest cost, so keeping a accurate MPG figure came right out of my bottom line!
In my present coach,1996 Monaco Windsor, 38', 8.3 manual motor, 3060 Allison, towing a PT Cruiser, running the diesel generator, last trip to Custer, S.D., in constant wind, 8.2 MPG! It was hot, so we ran the generator almost 24 hrs. a day! My old girl has a very good HP to Weight ratio, and with the tricks I have learned over all of the years, in driving the big rigs, I have got as high as 10.2 MPG, and the low was this last trip, at 8.2 MPG! I average around 9.2 for the time I have owned the coach!
Wind will affect the MPG more than any other factor!
No more miles than most people put on your MH a year, the MPG are the least important thing you should be worried about! Maintenance, and upkeep, are the things you should be worried about, when buying a coach, and will be the biggest factor in your bottom line!
Good luck, and don't sweat the small stuff! Rail!:cool:
