We can absolutely get your 2021 Ram 2500 4x4 set up with all the parts you'll need in order to flat tow; and I'll go ahead and list out the best parts for your truck:
- Base Plate Kit: Roadmaster Direct-Connect Base Plate Kit # RM-522204-5
- Tow Bar: Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar # RM-422
- Safety Cables: RoadMaster 64" Double Hook, Straight Safety Cables # RM-646
- Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267
- Supplemental Braking System: Demco SBS Stay-IN-Play DUO Supplemental Braking System # DM86VR
OR
- If Your Motorhome Has Air Brakes: Demco SBS Air Force One Supplemental Braking System # DM26VR
- (Optional): Roadmaster Tow Defender Protective Screening # RM-4750
The Roadmaster Direct-Connect Base Plates are great because they allow easy hook up for a tow bar, and have removable arms which allow your Ram 2500 to keep its clean look when you aren't flat towing it. The BlackHawk 2 tow bar is the best option because it has long arms which make it easier to maneuver when towing, along with safety cables guides for easy install, and a simple latch for simple disconnection, even on uneven ground.
I really like the Flexo-Coil wiring kit because it is designed to prevent any type of electrical feedback, keeping your Ram's electrical system safe. As for the braking systems, both the Stay-IN-Play DUO as well as the Air Force One are the best because they are a one-time install which will never require any type of removal or reactivation, and because they give you braking proportional to that of your motorhome. This results in much smoother braking than most systems which send out a pre-set amount of braking power, giving you a far more comfortable ride.
The Tow Defender isn't required, but is a really good idea to use because it will help keep the front of your '21 Ram from getting dinged and damaged from small rocks and road debris as you are flat towing.
