C9 fuel mileage

[Avalondanes]

I just wanted to know if my C9 is in the ball park. No toad, 40' coach, 7.4 - 8.0 with a best tank of 9.3 ( that whole 1700 mi trip I had great mileage 8.7 - 9.3 )

I think you are doing good we get around 6 pulling 6,000 pound toad with a heavy foot our coach has 2,400 miles on it not broke in yet

[Avalondanes]

I do have a heavy foot also, most driving at 70mph with over 30,000 miles on coach. The onboard gives average at 7.7 mpg for the running total. Pen and paper is higher per fill up on the road as the gen set is out of the picture. Just wanted to know if I could squeek a few more mpg's out of this set up. The more MPG's I get the more miles I can travel in today's economy.

I would say you are right in the ball park. I don't have the C9, but with the C7, pulling a 4,100 lb. toad, I get an average of 8.1 mpg.

[Avalondanes]

Is this all the C9 owners?

We are loaded for bear in our DutchStar 43' pulling a 4800 lb H3 and carting about 1200 lbs of HD and lift due to being fulltimers with nothing in storage. The best mileage was 7.3 at 70 MPH. The slower I went (down to 62-65MPH) the worse the mileage. So now I just put the hammer down and keep up with anyone and everyone.

Hm.. I have heard others say that slowing down does not seem to effect the MPG for their MH. That's contrary to my CAT 330 experience. Getting great MPG must have something to do with the MH design, weight being hauled around, engine design, engine torque, torque at the rear wheels and rear end ratio. None of this stuff can I speak to intelligently so won't go there. I keep good fuel records and rarely will I break 8.0 MPG and mostly that is when I a'm not towing our 5,400# toad, going down wind, and down hill. I have had my valves adjusted at 30K and I think that helped a little. So I am envious but have given up looking for the magic wand. It is what it is.

I too have a 330 Cat and the 7 plus MPH is all that I can expect. If I slow down it will be on the upside of the plus but at 75 I am very happy with 7. I don't separate the Gen. consumption from the total and I pull a 4600 lb tow.
