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 ????

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.
