Eric if you remember I had an 04 1500 QC with a Hemi towing my 28ft enclosed trailer. I was pushing it with the 1500 as I really needed a 2500. The Hemi did ok for me but no where near what a cummins would do and I got around 10/11 mpg pulling my trailer. If it was a 2500 I would have kept it but ended up trading it in for an 07 2500 with a diesel.
Call me Saturday and maybe I can go look at what you are interested in.
