I will give you some REAL world numbers. I pull a 2016 Open Range 3X377FLR with a 2020 Ram DRW 6.7 HO Cummins, Asian 6 speed and 4:10 gears. The FW grosses at 16995 LBS. I will guess the FW is around 15.5 K when I pull. On a recent trip from Northern Indiana to Central Florida 1256 miles one way.
9.4 mpg at 62 mph. 9.1 @ 65 mph. 8.1 @ 70 mph. These were hand calculated. The lie "O" meter was .1 to .3 mpg off (+-). In Florida when not towing Lie "O" meter 18.6 hand calculated 17.3, 50 - 60 mph.
Add another 10k and you will be right where I am.
