I have a 2001 2500 Dodge Ram cummings and would like to add a dully kit. I only want to put dully on the rear and leave the front wheels alone. I want to use my existing rear wheel for the outside. I am only doing this for stability and safety when pulling my 5th wheel RV. I do not want to increase the hauling capacity of the truck as it does fine now with the RV. I just want the dully tires incase I blow a rear tire with all the weight in the bed from the 5th wheel. Does any one know of a kit I can purchase.

 

Welcome! Lots of good info here.
