13.5-18 range TC and small cargo trailer. Cummins 5.9 diesel 24v. 64mph.
13 is into a 35 mph headwind.
18 is with a healthy tailwind.
Usually I see 15.5-16.5 range. Wind is usually present crossing the country in the form of crosswinds, which are worse than straight on winds since trailer gets the full brunt of it too.
Without wind I never see below 16.
Without trailer I should go up ½ or 1 mpg due to obvious lost weight and lost air resistance.

Pointing out the obvious variations is stupid here, but the big one no dummy points out is the size, shape and weight of the TC. Tall square ones are the worst, and folding ones don't really even count, but rounded and smooth shapes will yield the least wind resistance. Mine is rounded and smooth, so will always punch through the air smoother than the stick built square shapes most TC look like. I think I would lose several mpg with square corners.

Also, do you have junk strapped to the roof or not, to the back on a tray or not?

With the truck and camper in my signature,I got 13.9 mpg on a recent trip from Salem, OR to the Snake River in eastern Oregon, a little over 1,000 miles round trip. Quite a few mountains. I was a bit surprised as I only had 3,000 miles on the truck. Not even broke in yet.

BTW, is tailgating a semi truck now an approved way to increase fuel mileage?[emoticon]

This is the truck camper section, not the travel trailer section.

2016 Ram 2500HD - 6.4L Hemi gasser - Adventurer 80RB (loaded about 2480 lbs)
Georgia to western Canada and back, roughly 8,600 miles
Hand calculated (meticulously) for entire distance - 13.8 mpg

This is driving sedately at 60 to 65 mph. On one 170 mile stretch across Montana I got 15 mpg.

Fundamentally, my mileage is "blown in the wind".

2015 RAM 3500 4WD MegaCab SRW Cummins TD with an Arctic Fox 811 (roughly 4200# loaded) we usually average 14-16mpg. I tend to keep it at about 62mph most of the time occasionally a bit faster. The truck has 3.73 axle ratio. I routinely average 19mpg unloaded. I am a very light footed driver, loaded or unloaded.

That brings painful memory.
I had incident when Las Vegas winds lifted 4x8 plywood with my 215 lb on it and slammed us against stone floor.
Took almost a year to recover from shoulder injury
