Default Fuel mileage on my Cummins 2500

No load on my 24 valve is 18 mpg (no tuner) and is 12-14 on the same truck loaded (11,000 LBS 18' Trailer and load) using tow mode. Hauling a diesel is about the same weight as a 2500 Hemi (should know shortly).

The 2500 Hemi guys might could provide you mileage info.

Goose neck trailers weigh more (and draw the attention of the DOT).

Good luck..........R...
