3500 Ram 6.7/Allison 6 speed

New truck and new fifth wheel. Curious as to what type of fuel mileage I can expect. Truck is short bed drw/4x4. 5vr 36'. Headed out I10 Nevada to Florida. Any Thoughts?

Congrats on the new rig! I have a 2009 3500 that we used to pull an 11k lb trailer. Ran around 11 when loaded. In reality though the mileage didn't matter much as we tend to drive a couple hundred miles then park for a few days to see the local area. We leave WI the first week in Oct and take two months to get to Key West. Stay a couple months then the same thing heading north. Spreading to fuel costs out over the six months or so doesn't seem to bad.
Enjoy the trip!

Welcome to iRV2.
If yours is a brand new tow vehicle , remember the Cummins break in instructions, and that your mileage will not be at it's best till approx. 20K miles.

There are no break in "Cummins" instructions that I am aware of. They are ready to work right from the factory. RAM suggests you don't tow for the first 500 miles.

You should average 9.5 to start and improve from there.

Congrads on the new rig and truck!
You bought a 3500, That is the way to go. I use one as a service truck. It is a good engine and powertrain. Just remember the only way to save fuel is to park it.
Mine gets 9 ish pulling 10,000 lbs and 9 ish pulling my teton. 20,000 lbs. It really has to do with your speed. 60 mph is where mine likes to sip. 70 mph and I am beating the fiver and drinking fuel.

There used to be a recommendation in the Ram manuals regarding the use of cruise control for the first number of miles too. Cummins wanted to see the RPM varied for better seating of the piston rings.
It's been 7 years since I retired, so they may have dropped that from the manual.

I didn't know Ram was offering an Allison. I'm not a fan, but interesting. Plan on 9mpg and if you are lucky, you'll get more. Have fun.

Don't want to ruin anyone's day but Ram does not come with a Allison. They do have a HD trans option in the 3500, It's the Asian 6 speed and it is made to tow.

You are correct, and knowing the Asian was available , I breezed over the post topic line and missed that the transmission was miss-named.

I have not looked in my manual for my 2011 other than no towing for 500mi and that is for the gears to seat. Cummins says they are ready to work right out of the box.

I personally did vary the speed on my 11. I actually ran it hard up some passes and let it suck air down the other side.

Just an FYI the Aisin transmission is a true medium duty transmission.

The break in note is in the diesel supplement owners manual. It does state, do not tow for the 1st 500 miles. I hooked up our 16k 5er within the 1st 5 miles of ownership, and haven't stopped. 14K on it now, and we full time. I did change the rear diff fluid at 10K though.
