Just finished a 186 mile trip towing my enclosed 8x16 trailer loaded with appliances, 21 mpg (imperial), this eco diesel is so efficient, my 2011 outdoorsman with the Hemi did 23.5 mpg at best without towing and the best I did towing the same trailer was 13 mpg, exact same trip.
The speed limit 50 mph so I drove at 55 and let it go down to 50 on hills. I had it in tow haul at the beginning but it revs too much for nothing, I kept an eye on the transmission temp, it stayed at the same temp the whole way, it was also unusually hot today here in northern Ontario, it was 80 Fahrenheit, it I was in 8 gear most of the time, it shifted to 6th on a few hills, but usually only down to 7th. I am at 1000 ft above sea level, but having a turbocharged engine it is not affected as much as naturally aspirated engines.
