Hello,
New Ram owner here just bought a brand new 2015 Ram 3500 Dually to tow a 20K pound 5th wheel. Once I am past the 5-8K mile breakin, what kind of mileage can I expect at 55-65 MPH? I know air resistance increases fuel consumption exponentially, so anything over 60 MPH is eating up fuel, but I am just looking for a ballpark. Most of the towing data I found in a quick search were for 5-10K pounds.
