Bobi and Dick McKee Posted April 1, 2018 Report Share Posted April 1, 2018 We have a 2015 and I tow at 60 and get about 8.5 on a long level run. Throw in some hills and it drops into the 7's. Never checked it bobtail The trailer comes in at 21k. Link to comment Share on other sites More sharing options...
ewacowboy Posted April 2, 2018 Report Share Posted April 2, 2018 2007 M2-106 330hp Mercedes and 21k fifth wheel we're averaging 9.5 towing and about 12 bobtail. It will vary greatly depending on the wind. I set the cruise at 65.

ms60ocb Posted April 3, 2018 Report Share Posted April 3, 2018 With 2015 2015 M2-106 Sport Chassis towing 8 and bobtail 10. Bobtail is short trip and generally 200 RPM faster on the road. But I'm really hard pressed to gauge mileage using 2 fuel tanks and almost never filling them at the same place. The ambient Temperature makes a difference but I have no idea the difference being 20 degree or 70 degrees.

Clay I have the same problem - I get lazy and the store attached to the diesel pump looks like it might has a good selection of jerky to pick from so I wheel in and fill the one tank... Near as I can figure the little Cummins burns all the fuel I put in the tanks... Seems to do around 10-11 towing 16,500lbs x 40ft toymobile. It goes a long time bob tail...
