I would rather just believe it and be happy. Remember that the new Ram 4x4 2500's weigh 8000 pounds, 375 HP and 800 FP torque and they get in the upper teens highway easy. The new Jeep Wranglers get the same. What they can do and how they do it just blows me away.

I see guys around here towing stuff I'd never attempt to tow with a 3/4 ton truck with 3/4 ton RAM 2500's. They sell a lot of air bags around here.
If your trailer don't drop you to the bump stops I'd not worry about it. If you are hitting the bump stops get some air bags.

Yes I did, see post #4 as I found out the app I was using also gave incorrect readings! Here is the human calculated mileage for that trip, 11.41 is 20.6/usg or 24.7/imp.g.

My formula is like this. For Imp MPG is 282/LT per 100 KM. And US MPG to Imp MPG is 5/6
So 10 LPH is 28 IMP mpg and 23 mpg US.

Mine gets between 20 and 21 mpg, hand calculated, on hiway trips. Towing between Weatherford and Greenville last weekend, I got 13.2 mpg, again hand calculated. My 5.0 F-150 got similar mileage not towing. Towing it got between 7.5 and 10.5, depending on wind and hilliness. I always tow at 65 mph or less, unless I hit 70 passing a truck. I do like to get out of the way.

That's what I get with my Ram. At least you tell the truth with the Ford.

Something I forgot to mention in my original post was I have been a true and true GM guy and had a Chev 2500HD work truck, 2008 and a 2011 and my average mileage was about 14.7l/100 km! I took the plunge and got the Ram and mileage wise very happy thus far. Thinking though the ride may still be in favor of the Chev.

I've had my 2500 for 2 years, model year 2014. The mileage is nice, relative to the size of the truck. But the down side as been DEF, RAM has a small reservoir and needs to be topped off at least 1 for a 1500 mile trip. I commend RAM for putting a DEF gauge on the truck's instrument panel but the movement isn't linear, it goes down in bolus steps, ergo I'll top it off at the first fueling after going past midpoint. Another unpleasant surprise was the frequency and expense of the fuel filters. The fuel filter change first change was at @7000miles and >$300. At 7000 miles oil life was still at 50%. Others filter changes have not been as soon but no where close to the oil change interval, all according the the vehicle CPU.

Interesting. I haven't had the truck long enough (only have 4000 km or 2500 miles) and the DEF gauge has barley moved off full. The Chev I had did not have a gauge, only a short indication that you had 1600 kms to go before empty. Then about 200 km later it would alarm and say you had 1000 km to go, then 200 km later it would say you only had 500 km to go! So GM didn't have the most accurate system in that 2008-2011 vintage either. At least Ram has a gauge you can see what's happening.

In my '14 Dodge RAM 2500 Cummins, the DEF is used at a rate of about 6% of fuel use. For every one gallon of fuel, .06 gallons of DEF is used.

Also, on my truck, the DEF gauge can go well into the red without any fear. I wait until the needle points at the red, then by a 2.5 gallon jug of DEF and refill it, bringing the gauge to about 3/4 full. You get plenty of warning that you need DEF, and the 5mph limit is not something that is sprung on you out of the blue unless you have a problem with the DEF system itself, not the level of DEF in the system.

I've also been using the WalMart house brand DEF with no problems after four jugs.

The fuel/DEF ratio is 50:1. So at 12Mpg you will get 600 miles per gallon of DEF. The tank holds 5.5 gallons of DEF so you will get about 3000 miles towing at 12 MPG. I see the DEF as a minor issue. The 2 fuel filters are about $65 each and I change them myself. They are done every other oil change or every year for me. These new diesel trucks cost more to operate but the ride and power are great. They are quiet, heated and cooled leather seats, push button start and the list goes on. Will be my last big diesel pickup.
