With 9000 miles and AV flash yesterday I drove 65MPH for 100 miles on Interstate with cruise all the way and got 15.9MPG hand calculated. The overhead was mostly 17.0... Best I have gotten so far.[&:]

 

what was it b4 the flash?

 

Trip was today.

 

realy sounds like the 6.7's arent going to get the mileage the 5.9's did.

 

I got 14 mostly city on the 6.7l with lots of idling to warm up the motor so far..

 

All that idleing is not good for your engine. You only need to idle a couple of minutes then baby it @ 1500 rpm's or less for a few miles.

 

Have you pulled the Cedar Creek much yet. My mileage slowly rose over the first 12-15K miles. It seemed to get better each week after towing my camper on the weekend. I'm now at 49K miles.

BTW, I filled up the other day and got 20.1 on the last tank hand calc. First full tank after a 500+ mile trip pulling the camper. Got 11.05 average for the trip while pulling.

 

We have made 8-10 trips with it. I had 06 Cedar Creek 36' before this Day Dreamer. We towed it with my 06" dually. http://www.gorowan.com/2006ram
