The truck companies dispelled that myth a long time ago. Some big operators have governors on their rigs now or keep track of speed through satellites.

I made the price of oil go up!

I just filled mine up for the first time to discover that I was getting 5MPG on my unit. I was a bit disturbed as I only went 65MPH max. I do however keep a log and since it is a new unit I had to take it back to the dealership to get the punch list taken care of. When I dropped it off at the dealership my generator had only 5 hours on it but when I parked it the generator had 22 hours on it. I am hoping that is the cause of my low mileage.

We just tested ours. We averaged 8.89mpg over 4k miles at 65mph. Now we are getting around 13 at 59mph. that is a 20,000lb unit towing a 6,000lb toad. Our 6000 Cummins generator is always on so the kids can watch tv. It burns .2 at low, .4 at mid and .8 at full capacity. If your generator is anything the same and you were at full capacity, figure 13-14 gallons of gas. The generator is definitely a consideration.

Had a f350 v-10 12 mpg at 60-65 vs 10.5-11 at 65-70. Towing a 2011 Forest River Wildwood Sport with quad ~13k 7-8 mpg depending on hills (PA). Towed at 45-60, again hills and I do not push it.

Just completed driving from VT to AK in our 2011 32' Greyhawk and averaged about 9 miles per gallon. We had 1000 miles on it when we started. Staying at 55-60 mph is the key. It may take slightly longer, but what's an extra day when your lodging is with you.

Were you towing anything?

We just finished a 6,100 mile trip up the east coast from Florida into Canada & back. Lots of hills on the route we took. Kept around 60-65 MPH depending on the roadway. Towing a tow dolly with a Lexus on it. Had it all weighed at the start of the trip (loaded) and we were just under 24,000 Gross, which included the tow dolly & Lexus.
Over-all average MPG was 7.1 We would have liked it to be better but it is what it is. Next trip we are going to try and keep it around 55 to 60 and see what the difference is.

I am still getting around 6 MPG on mine and I made the discovery that my speedometer is off by 3 MPH so I though I was going 65MPH when I was only going 62MPH. I am not running the generator nor am I pulling anything. The Ford dealership said it may be the way it is geared. When speeding up if I keep the RPM's at a normal rate it takes me about 1.8 miles to go from 0 to 65. My tanks are empty with the exception of the black water tank which has 2 gallons of water and the chemicals.
