2018 Ram 2500 deisel megacab cab
Normal freeway - 22 mpg
Freeway in the semi Lane - 27 mpg
Towing a 30 ft camping trailer -11 mpg
This mileage seems considerably higher than what I've been reading online, which trends in the teens. I wonder what gives.
Why not switch off or blank the dashboard display, and imagine you are getting 30 mpg. You'll be even happier then! Only way to get a proper figure is to plug your stats into Fuelly and see what you are really getting.
