I have a 2017 Ram Diesel, 68 RFE Transmission, Crew Cab, Short bed, 4X4 with 20" wheels. We want to purchase a Fifth wheel trailer but the pin weight is over the recommended limit. I have checked and believe the rear end housings to be the same on both the 2500 and 3500 except for the spring set up, leaf vs coil. Am I right that the housing and gearing is the same, if so I want to install a Firestone Air Bag system to better support the additional weight. Has anyone had experience with this set up? If so which Firestone system is recommended or is another manufacturer recommended.
