Bought a 2014 2500 blackout on 9/25/14. Warrantee is extended for a couple more years yet toying with the idea of deleting or emissions intact.
Mods (if you consider them) : Waxoyl Undercoat, Running Boards, Tonneau Cover, Offset Wheels for the Summer. Soon to be Power Folding Tow Mirrors
Thoughts: Primarily interested in transmission tuning for the 68RFE which is somewhat of a joke in the 2500 segment
Future(post-warrantee): ARP & Delete & Straightpipe dump (electronic valve) & Air Ride

Looking Forward to the knowledge, particularly from DRD
