6.4L Hemi/4.10 towing mpg

Towing this 37' 5er at 11.5 or 12k fully loaded for a 3 week trip:


About 21000 GCW (correction - It weighed in at just under 20k)

I got this over 291 miles:


And no, I didn't go 62 mph the whole time, that's an average over almost 5 hours where I made a couple fuel and bathroom breaks and because of this, had to do some city driving. Cruise was set at about 68 mph.
  • Mostly flat, not much for wind yesterday, ran 89 octane as an experiment. Hitting the hills and mountains today. I will try to get some video as I tow up the mountain grades.
  • That's not bad at all... Relatively flat land or any hills? My buddy just bought a 2015 6.4 and he tows about 7000 lbs bumper pull in the Appalachian hills of central Pennsylvania a lot. He doesn't get that good of mileage.
