Recommended Disc Brake Conversion for 7,000 lb Dexter Axles
Question:
Planning to do a disc brake conversion on our 2018 Montana 3791RD. TV is a 2017 Ram 3500 DRW and Cummins 6.7. Is the controller in the vehicle compatible with the hydraulic actuators in your kits?

On your 2018 Montana 3791 RD, with Dexter 7K axles, we do have the parts but not in a kit for axles that large.
I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 7,000 lbs # K2HR712D along with Bearing Kit # BK3-100. I recommend using grease # L11390 and cap # F001520 instead of doing the oil bath simply because if a seal fails you can melt your bearings and cause more issues than what grease would allow.
Then for the electrical aspects, I recommend the HydraStar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes - 1,600 psi # CAR-HBA16-2. The controller in your 2017 Ram 3500 DRW is not the best for these systems, so I recommend the Tekonsha Prodigy P3 # 90195 and wiring adapter # 3024-P.
Let me know if you have further questions. I've attached some articles to help further.
