14 mpg pulling 14k 13’ tall brick and 20mpg with a 4klb 12’ tall brick?
cmon man….Ford should buy that one back from you so they can see what they did to make it get better mpgs than any truck in history!
um 3K, 10.5 foot tall brick, get it right . sorry just looked up the camper milage and that one was for a canadain gallon of gas, not your small US gallon 😁so the actual milage was 14.1L/100km which works out to 20 miles per gal Cdn, or 16.7 miles per gal US. but the 5th wheel is bang on, 14mpg US, 16.8 mpg Cdn or 16.8 L/100km. thoes were from this summers trips. part of it is, normaly when I am towing the 5th wheel I am doing 55mph and running the 45hp towing tune. when I am hauling the camper I do 60mph sometimes but normaly 55mph plus I run the 100hp tune when hauling that. I don't know if you have ever hopped up your diesels, but if you did you would know the more you hop them up the better milage they get if you drive it the same.

I’ve tuned a few. Depends on the truck, the year, other mods and the tune.
But you’re getting record setting mileage out of an early 6.7 Scorpion especially with emissions in tact.
55mph does help. But gdamm I’d fall asleeep or go crazy driving that slooooow.- StirCrazyNov 08, 2025Moderator
haha, the speed limit is only 60mph for most of BC (coq is 70) so its not a strech to only do 55 when your twisting around and climbing mountians.
it has always gotten deicent milage stock it got 18.3 mpg (US) going to work and back, my buddies were all averaging about the same. after I tuned it that dropped to 21.3 mpg (US) and when I do the delete I expect about 23MPG or better but thats just guessing. that is driving at 70 Mph to work and back average. I think my best run empty since it was tunes was driving to edmonton and back doing the speed limit and I got 23.5mpg US.
maybe our fuel is just better up here, I know it has more lubracation in it, which is why our cp4 failure rate is the same as england at less than 1% where the failure rate in the US is over 7%.

I always get better gas mileage (I have a gasser) when traveling through Canada to/from Alaska that I can't explain. The slower speed helps, but I've always wondered what is different in the gas, no ethanol maybe?
