New Coach-Mileage??

We just bought a '06 HR 40 foot, with a 400 Cummings the coach weight is 33,000 and we plan on towing a '13 Kia Soul, 3,700 lbs on a tow dolly.
I have heard we can expect between 6 and 15 mpg.
I have never had a diesel so I have no idea who to belive, but I know I can trust people on this fourm, that have done the traveling.
What kind of fuel milage can I truly expect ????

Hey Larry...congrats on the purchase of your new HR. Depending on about a thousand different variables ranging from where you drive, to how you drive,to the barometric pressure, your mileage will be probably be around 7-8mpg. In the couple of years we have been FT in our MH, I have never cared about mpg's! Please tell me you didn't buy a 33,000lbs. MH expecting to get great mph.....phone your credit card company and have them bump your limit....you'll need it every time you fill the tank.

Hi. I just bought a 2005 Newmar 40ft with the 330 Cummins in it. I weighed it on the weekend and it weighed in at 28116 lbs.. full of fuel,
full of propane, No water in it.. I did 1 trip 300 miles and got just over 8 mpg. Last weekend I went 130 miles
towing a Dodge Dakota behind it and got just over 7mpg.
My speeds were what the traffic allowed. from 55 mph -70 mph.
most times it was right around 60. A heavy foot is bad for mpg. but when its a big hill you will find your foot is to the floor.

We have a 400 in our 06 GS running around 30k most of the time. In the time it takes to use 100 gallons of fuel I have usually run the generater some so my reading seem to never be purely road miles, usage is rarely over 6.9mpg. I do like the 400 Cummins so far and would prefer nothing less if buying again.
