I run @ 68 and get 10 mpg, when I have to run slower it goes up to around 12mpg.

 

Consistent 16mpg towing 27ft/5k Baja boat loaded on mostly hwy w/some stops and hills in central TX. Can't complain at all vs. the mpgs w/a Dodge1500 gasser(8mpg) on the same route.

 

9-11 MPG with Forty foot Warrior loaded with gear and a Toyota Land Cruiser. You guess the weight.

 

Last year pulling a 28ft Jayco Eagle 5th wheel I was getting 13.8 mpg. u.s.[9000 lbs]. We just purchased a 2008 Montana,36ft long and weighing in at about 12,000 lbs loaded and on our last trip averaged 14.4 mpg u.s. The Edge Easy was not installed on this trip. Our speed averaged was 60 mph & our milage is at 62000 KM [39000 miles].

 

Wow! Hell of a rig...

 

Just came back from a trip down south pulling 8000 lbs. It was 98-100 degrees out and I was doing about 70. Got 13 MPG with my 02' 2500.

 

Drove out to the Black Hills this weekend and averaged 11mpg. This was a 3600lb. equip. hauler flatbed with about 3000lbs. of ATVs on it.

 

Made a trip down to the Texas Coast (Galveston) back in July pulling a 28ft TT. I made note of mileage going down 11.6 mpg and return trip showed 12.5 mpg all hand calculated.

I see about 10-11 with my 10k TT in the mountains - there's a nice 7% grade that we climb for a few miles. Hand calc'd too..

 

I get 15mpg on my 9100lbs GN empty and with about 12k on top I get 10-11mpg

 

'Bout 16mpg towing my 6500lb boat, but not much wind resistance there. That's a steady 55-62mph as the road wasn't an interstate.

 

When empty ('03 3500) I get 20mpg on the freeway. When hauling smaller trailers I average 18mpg (maybe 2-3000lbs.) When I have the 40 ft 5th wheel on it is 12mpg (16,340lbs - total combined weight 23,750.)

 

I pull a 30' Flagstaff with a GVWR of 7700lbs...
I averaged 13.1mpg through the blue ridge mountains at about 60mph on straight runs...

The Banks Big Hoss Bundle really saved my fuel economy...

 

great mpg folks. You should hear the PSD folks over on RV.net whine when the Cummins owners report our mpgs. The first truck owner that hollars"liar"is always a PSD owner, especially the 6.0 folks.
My '03 2500 HO NV5600 3.73 towing my 11200 GVWR 5er averaged 12.5 mpg on our last trip through TX/NM/CO/UT/WY/MT. Empty mpgs will average 21.5+ on my 600 mile a week commute. All pencil figures and are averages and not just best tank mpgs. The Cummins inline 6 cyl diesels have always gave great mpgs compared to the compitition.

I pull a 16FT Gn landscaping style traler with 2 1600lbs zero turn mowers along with other junk om trailer and last 2 fill up averaged 10.84 and 12.56Mpg last tank had some miles without trailer
