On our way home from Overland Expo I got 15-16 mpg.
3500 Chevy Silverado diesel.
I probably average 14-17 with the camper on.

Overall mileage on my gas f250 is just over 12, most with camper on. I try to keep it below 65, like longhorn mileage suffers above that. All history available in fully link below.

Ah...you folks are quoting pavement mileage...how about off road?  

 

I know it really is only an academic discussion; cuz it doesn't matter.  When you need fuel, you fuel up and pay the piper.

 

You play you pay.  Only reason for me to guess what my mileage will be is to plan my off road trips where fuel stops are few and far between.

 

Short off road trip [100+ miles] with new Hawk on '05 Tundra A/C  SR5 4x4 [ about 6,900+ lbs GVW] ...12.7 mpg, of course your mileage may vary!   :D

 

Oh yes, I never run OD anymore; hate to run the 4.7 motor at 2K rpms pulling this weight.  Try to not drop below 2.4-2.5K on level and 2.8+ going up grades.  just me.

just wondering what do you get if you are doing 75 mph? How much does it drop off?


Sent from my iPad using Wander The West

I never drive that fast but at around 65mph it drops off to about 14-15

I now have 9700 miles on my 2016 F150 with 3.5L EB (gas) (specs in sig) in my first 3 months. I have 12.8mpg lifetime so far.

Every tank fill was recorded and corrected for tire size/speedo error with basic notes on load conditions. 8700 miles of that 9700 was carrying the Hawk and most of it also towing my boat (18ft Alumaweld fishing boat) from Seattle to Phoenix to Florida then back home via Denver - so windage, mountains, and carrying max payload :-). It happens that the displayed mpg matches very close with my corrected numbers due to canceling errors and corrections.

I lose 3-4mpg going from 55mph to 70mph. Saw almost 18mpg doing 55mph down I-5 from Redding to outside LA (400 flat miles). Everywhere else was mountains and 70+mph speeds and some high winds in the plains states. Without the large headwinds I can eek out 14mpg on flat ground at 65-68mph.  The key is to keep my foot out of the turbos, hard to do :-)

2012 Ram 2500 w/ Hemi gas and 3.73 axle. Now that we put the Flatbed Hawk on lost about a mpg down to 13 mpg @ 65 mph.  My guess is more weight and higher profile than the slide-in hawk we had before. Still worth it.
