Looking foward to a video. I always enjoy watching them. I used to get 18.5 around town with my Cummins Rams and 14~ with my gassers around town. Folks don't believe that either. Four 6% grades in an entire trip isn't quite what i had pictured. Still seems a bit easy on fuel for that much weight with any truck.

I believe you on your numbers hannibal but it is a pretty big stretch getting the mileage he is getting in those climbs. I will have to see some other kind of proof also. There's a difference between 6% for a few hundred yards and 6% for a few miles x4.

1 pull is 9 miles, 1 is 6 miles and the rest are considerably shorter. After topping the rim it's about 60/70 miles of rolling hills requiring 10 psi boost or less. My cooling mist helps also. roller183 has a 12 Ram dually and a BIG, 40', 3 slide toyhauler. He said about 17K loaded and he gets around 10+ as I remember. Ring him up and ask him. We met here and found out he lives nearby and probably will be going with me on Labor Day.

Hannibal. you #'s on your Cummins seem about right with someone not pounding on it and knowing how to drive. Driving style will get you good mpg's. But from what I have learned the Cummins seem to be better for fuel economy.

As for further proof all I can do is tell you to check out an Az topo map and check the elev along that trip. The first 110 miles have the 6% pulls. I start @ 1200' and topping the rim @ 8200' then down to 6500' Not hard to figure it out.
It's not a problem if you don't believe me, I have nothing to gain by bs'ing you now do I?
