Thank you gentlemen - appreciate your replies.

With all respect. Assumption would be you are new to diesels and given your truck is a dually...

You should take a little time to read up in your manual and countless threads on here regarding towing and general exhaust brake usage on these rigs for proper emissions functionality.

Good luck. Beautiful truck.

Thank you sir - true that. All information is good information. I had 2 older blue oval diesels in past years but this is my 1st Mopar and 1st Dually. Bought it last year with 97K miles already deleted, rebuilt front end with DynaTrac & Dana parts, and installed lockout hubs. Drives like a new truck and snaps me back in the seat when I poke the throttle.
