How on earth do you get 25 MPG highway? You double your MPG from towing to highway? Remarkable.

I also have a '14 Silverado Duramax.I have gotten 25mpg babying it on a flat interstate no trailer.
Usually average around 20-22 no trailer'
Around 18 in the city no trailer
With my Freedom Express behind I average around 14 to 15 @ 60-62mpg.

Also DW wanted a newer vehicle so she picked out a 12' Ford Edge SEL and that piece of crap gets 15 around town. So i figure if she was towing the little red wagon it would be about the same as my Duramax. Pathetic.

I have been a GM truck guy since the last Ford in 1992. Bought a LaCrosse 329BHT and it totally overloaded my 14 GMC Sierra 1500 4x4 so I went truck shopping for the second time in a year. As much as I liked the 14' 1500 I didn't like the 2500 gasser or diesel. The 6.0 felt slow and really had to rev to get anything moving and downshifted at the drop of a hat. The Durmax was a lot stronger but the truck had a lot of vibration and I hated how the DEF tank was mounted under the truck almost behind the right front tire waiting for road debris to knock it off. A buddy of mine talked me into looking at the Rams and I ended up buying one. Very nice interior, the controls are well laid out, and the Cummins is a towing beast but still easy to live with on a daily basis. Towing at 65 to 70 it gets 12 hand calculated, empty on the highway over 20, and about 16 around town. Besides maintenance being a little higher than the gasser, the only real drawback is you have to shut it down to order food at a drive through otherwise there is no telling what you are going to get in your order. The Cummins sounds like a real truck.

I read a lot of stuff folks post & I've researched Dmax forums a lot. Just pick out the good points of advice. I got 25mpg going up the WVa Turnpike and back down but (new w/>1500 mi)..... I kept it within the speed limit (under 70). I used to run 80+ but not anymore with vehicle prices what they are today (I'm also older ). Take care of your vehicle and it will last you a good measure.

Just keep your foot out of the accelerator, learn how to work that DMax and Allison Tranny. My commutes to work through Raleigh NC get me 18 - 20mpg average and I'm keeping up with the flow of traffic. Learn shift points, don't tailgate, light jump or hot dog it and you will get the same mileage.

When towing, find that sweet spot where your rig settles in at and you can cruise comfortably and get great tow mileage. Shaving 20 min travel time isn't worth an extra $20 in fuel, DEF & other costs. Towing isn't all about HP and Torque. Nothing will overcome the aerodynamic effects of towing a large brick through the air. Read many ramblings (GM Eng commenting as well) that if the EPA weren't such idiots, the DMax's could be getting 30mpg easily. Reading how the EPA sets emission test standards supports this too.

Most important; DONT FIGHT - WORK WITH the design the engineers put together. You will be happier and save $$ in the long run. This goes for ANY Brand!

Nope! Nobody listens to the common man anymore, it's all about the dollar. My last truck I handwrote 4 pages of comments attached to my survey I returned in the mail. GM actually called me to review some points.

Some things I remember;

- Get away from the CAD stations and hit the clay studio, realize there isn't but so many ways to design a truck. It is a working man's tool.
- Make stake pocket holes large enough for 2x4's again
- Bring back Wing Vents & Floor vents. No need for A/C most the time with those.
- Bring back the under-the-dash A/C (Freezer). Self contained modular unit that can be benched for repairs vice ripping out entire dash to replace a 10 cent part.
- Put back the flat bumper one can use as anvil or surface to hammer against not plastic.
- bring back the metal straps tailgate rests vice thin braided cable.

Couldn't explain to them a Truck is a working man's tool, not a preppy-mobile or redneck junk wagon. It helped the Blacksmith shoe horses with it's features designed in the body, It helped the rancher/farmer string up barbed wire fences using a 2x4 to hold the wire rolls and tension the wire. The carpenter had a portable workbench with the tailgate till it got to frail and weak.

Nope, the auto industry lost sight of what we need long ago
