Since we are the only ones on this forum with a 2014 Ram and the STC, I think, you must be talking about our rig.
Just wanted to give you an updated MPG number. This past summer we did the AK/Canada trip from VA, ~13500 miles. We were FULLY loaded with 4 people for 64 days, usually carrying 5-10 gal extra diesel, so no light weight trip.
My hand calculated MPG overall was 11.75. Now this included lots of 75mph into a strong headwind(thanks ND where we were getting around 9mpg) and well over 1000 miles of 5-30mph gravel roads and frost heave accel/decel. The best we saw was a stretch at 12.42 MPG.
Also around ~866 MPG of DEF. So, more reasonable driving conditions and lighter weights might get you a much better MPG.
I have all STC and stuff weights, and mileage numbers in spreadsheets if interested.
