I'm not referring to you. By default, people are responding to the OP.

Oops, my bad. Carry on...

Haha, If you are referring to me, you better do a little fact finding. That was not my first post. And just to avoid further confusion, this is not my second post... :p

Gonna have to raise the BS flag on these numbers. Take 5 mpg off of them, and then they are realistic.

No the numbers I posted are real for that vintage Dodge/Cummins 2X4 with manual transmissions.

I tow a 12K+ tall 5th wheel with a 2001.5 Dodge/Cummins 4x4 with 4.10 gears and auto, which averages over 12MPG between Washington and Arizona. Get 19-20 empty on the road at 60-65.

Everybody will get a little different mileage. I live in the Texas Panhandle, and pull to South Fork Co. for the summer. Going up I get poor mileage due to 2 things. We are constantly gaining altitude, and late May there is usually wind. Wind is a killer on pulling as well as solo. I was surprised at how much altitude would affect the truck's mileage. Yesterday I was solo and drove from Southfork to Monte Vista to go to church. The 6.7 was making 22.0 mpg. A 40 mile trip. Coming back gaining altitude again with a wind against me, I was making about 16. Just can't come out and say this is what they will make. Get the truck you really like with the trailer you like that will match your trailer, and enjoy regardless of the mileage.

Interesting first post.

With fuel mileage there are things that you can do to the truck to improve mileage, like a free flowing exhaust, ECM tuners, air intake mods, but their return on investment will take miles to recover.

The most effective improvement on your mileage is learning to tow efficiently, that is the way you drive.

Avoid long idles, hard acceleration, and learn where your sweet spot in the torque band for your truck transmission and camper are, and slow down. Whatever the posted speed limit is I rarely go over 65 mph. Speed is the most determining factor of fuel economy.

........ and most important...what color.

Yes. Has to match the trailer. Bottom line. :)

06 duramax 2500 or 2002-2006 cummins

our 2002 / 2500 cummins 5.9 auto loader turned in an average over 157,000 miles at 19 MPG. we towed many miles at 14k equipment trailer, a 25' big foot TT, and used it as a run around daily driver.
