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. It's a good eng. I just prefer the Ford truck. And have tuned & modded my truck for towing only. I don't need a hotrod as I only use it to tow. Why I only have 150K on a 99.
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?

I'm hitting 10mpg towing my #6500 HTT.

I would love to see if someone has done the hand calculations to find if there is a noticeable increase in MPG by running 89 octane.
For the person asking about MPG, I get about 7.5 to 9 depending on wind etc with the camper in my Sig. I did have one miracle trip coming back from coco beach with what must have been a tail wind the whole way where I just broke 10 mpg.
With my previous '93 Sunline low slung 6,000GVWR trailer I used to break 10 every now and then but that thing sat so low it was about even with my truck topper.
I know I have the largest truck equiped with a Hemi but I would be very suspect of anyone that claims consistant towing MPG in the double digits with a full size TT.
I average 8.5 MPG towing our 30' fifth wheel.
The 5.7L Hemi in my Power Wagon recommends 89 octane for normal driving and premium (high-octane) while towing:
"When pulling a heavy load or driving a fully loaded vehicle when the humidity is low or the temperature is high, use a premium (high-octane) unleaded fuel to help prevent spark knock."
Living in AZ, I tow in low humidity AND high temperatures. When I first purchased my Power Wagon I followed this and used 91 octane while towing until someone on another forum said it was not necessary and I was wasting money, so I tried towing with mid-grade 89. Well, the difference was quite noticeable. I had always been able to tow our fifth wheel on 260 on the grade to the top of the Mogollon Rim in 2nd gear. With mid-grade I was down into 1st gear with about a mile to go to reach the top. Back to premium for towing and the next trip (and subsequent ones) I was once again able to keep it in 2nd gear and maintain a higher speed to the top. This last spring the temperatures were a little cooler and with the price of fuel I again tried mid-grade and again I was down into 1st gear with about a mile to go to reach the top.
I didn't notice much difference in MPG, but there was a definite improvement in performance. I will be towing with premium fuel from now on.
Wow! Now I know why I changed from a gasser to Diesel!
Premium fuel to tow and only getting 7.5 to 9 mpg. I can't make a statement on the grade on 260 never been there, but 1st and second gear??
My Cummins is a daily driver 12 mpg towing (12K 5er), 14 city, and 20 mpg @ 65 on the open road.
Lately I did a short pull to Sanibel using only 87 octane because I had crank slap and actually wanted as little power as possible while we squeezed as many miles out of the current engine saving for a rebuild.
The largest incline I had to worry about was the 1st Sanibel Causeway bridge which is aout a 6.5% or 6.6 feet every 100 feet to be exact-ish grade for a whole whopping quarter mile up. BUT, even with engine issues and 87 octane, it roared up it just fine. You don't need high octane to pull but from the account pulling up 260 (I'm not familiar with that either), it sure seems to help. It may be an altitude and humidity thing like the poster said. Forced induction may help with that too heheh.
Around 8 or 9 is the norm for a gasser. That is well known. It's also well known that turbo diesels get better gas milage. None of this should shock anyone really.
What I would really like to see is a comarison of towing with an ecoboost on 87 and 93 octane.

That pull on 260 is hard. It's a 2 lane rd and one 6% is about 8/9 miles and another is 5/6 miles of 6%. That's what is posted but it's steeper than the 17 miles of 6% on I-17 going north into Flagstaff. And the altitude isn't high enough to get out of the high temps. I have pulled it in temps over 100*

Wow again, I figured that that was like 8 percent plus! We have several 6 percent plus grades in western Oregon, and with 11.5K in tow I can still accelerate up them to the speed limit of 55. One on the coast has a 25 mph corner at the bottom.

We have a short one on hwy 89 between Wickenburg & Prescott. 6/7% only about 4 miles but with a bunch of 20mph switchbacks. On the brakes, on the fuel, it will work your truck pretty good. My friend tried to pull it in dr with his Dmax and the Allison was hunting the whole way. Temps were over 100* and his trans got up to 260. I had to school him on finding a gear and stay in it. No damage but a close call.
260 from Camp Verde is posted coming down @ 6% but I think it's steeper than that. Sure feels like it.

Good, I hope it serves you well. My old 99 is like new (151K) so @ 62 I think it will outlast me. Only put about 4/6K a yr on it towing is all it does.
Do the dpf delete and put a Spartan 200 hp tow tune in it. A friend has a 450 set up like that with 4.88's. That thing is a tow monster.

It looks like you can't even agree with yourself. ![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")
I agree that diesels get better mpg that gasoline engines. But that gap is closing with the push for more power and better emissions.
I get 11.5 towing 13K+ through the mtns
And I never said I made more hp. My 7.3 was rated @ 250 and with my mods I've gained about 80 more. BUT it will out tow a gasser with equal wgt. But I will never convince these gasser owners till one steps up to a contest. Don't believe everything you see on youtube.
The thing is, you can't pull more weight faster without making more horsepower.
Work is force applied over a distance. Power is work divided by time. More weight faster requires more power. Fuel choice has nothing to do with it. The physics is true for steam, electric, gas, natural gas, diesel, or anything else.

I'm no engineer but I do know what my truck will do and I dare someone with a gasser to tow my trailer up the same grades at the speed I do. Won't happen

Don't look for me to take the dare. I quit racing a long time ago.
I am an engineer and am just stating the obvious. Maybe your truck makes more power than you think it does. Whatever it is, it makes you happy and you should continue to enjoy it.
