I just bought an 2015 F250 4x4 6.2L (gas) I am thinking about buying a programmer/tuner for it. I am planning on taking the truck pulling a 28' camper to Florida this summer. My goal is to get the most gas mileage I can out of the truck. Does anyone have any recommendations or experience with programmers?

 

SAVE YOUR MONEY!

When I was buying my 2014 6.2L, I thought about buying a tuner because I pull a 40' fifth wheel RV. HEAVY!!! I go from Los Angeles to Denver in Spring and reverse trip in Fall with a few detours on the way because we live in a beautiful Country. I truck pulls GREAT! Yes, it is true when pulling steep grades... I am in 1st gear, 3500 rpm, 25 mph. I am willing to except that speed on steep grades. On level ground, I pull about 60 mph for safety reasons. I could go faster on level ground but this is how I drive... safety over speed. Anyways, my truck is perfect for me.

 

I am curious what type of mileage do you get?

 

Level ground towing... ~10mpg
Level ground not towing - last weekend from Las Vegas to Los Angeles @ 72mph... ~15mpg

In mountains towing... ~6-9mpg
In mountains not towing... ~11-13mpg

 

 

Weluv, how much does your toy hauler weigh? I ask because I'm looking at getting a 5th wheel that has a dry weight of 12800 lbs, I have the 4:30 rear end, but I'm still a little concerned about its ability to tow this, some of the trips will be in the Canadian Rockies, plus we live at a altitude of around 3300 ft.

Any thoughts or experiences would be much appreciated.

 

Looks like 3.73 gears. When my truck is north of 70 MPH like that the RPMs are over 2K.

My toy hauler/pop up is in the neighborhood of 3,600 with out a toy and I believe it max GVWR is 6,000 with payload.

 

Fireman - you might be interested in reading the thread "3.73 to 4.30 conversion question". Several of us posted what we are pulling (with weights) in various conditions. I have pulled a 10k-12.8k 5er for 13 years now with both a Chevy Dmax and now a F250 6.2L.
