Recommended Supplemental Braking System For A 2021 Jeep Wrangler Rubicon
Question:
Thank you very much for your response. I appreciate being able to ask an expert opinion. May I ask you why you prefer the Brake Buddy Stealth Supplemental Braking System - Proportional over the Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor - Proportional? Also, thank you for the recommendation of the Roadmaster Falcon All Terrain, Non-Binding Tow Bar. I was leaning toward the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights - RV Mount - 8K. Would you also recommend that one?

The Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor - Proportional # DM86VR and Brake Buddy Stealth Supplemental Braking System - Proportional # HM39530 are very similar systems with only a few differences. The first one being the cost, the # DM86VR has a higher cost than the # HM39530. The # HM39530 comes with a charge line kit which will keep your vehicle's battery charged, whereas the # DM86VR would require you to purchase a charge line kit like the # RM-156-25 separately.
The coach brake light must be on for the # DM86VR system to activate the towed car's brakes whereas the # HM39530 is going to activate the brakes proportionally to your coach's brakes using an inertia sensor. For example if you slam on the brakes in your RV, your towed car's brakes will activate with that same harsh intensity and if you gradually slow down as you approach a red light, your car will steadily brake in the same light manner.
The controller for the # HM39530 also doubles as a trailer brake controller so you can use it to pull a boat trailer, utility trailer, etc. without having to purchase a separate brake controller.
The # HM39530 is going to mount in the cab of the your Jeep and is quite bulky whereas the # DM86VR will mount in the engine bay with a small actuator and G-Force controller in the cab. If space is an issue the # DM86VR has the # HM39530 beat.
Both of these are great options but for these reasons I personally go with the # HM39530. There's nothing wrong with going with the # DM86VR if that's what you'd prefer though. If you do prefer the # DM86VR you will need the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 which will have 6-way to 7-way adapter cable and port for your vehicle or the Roadmaster Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights # RM47ZR and Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 if you have ParkSense Proximity Sensors.
For the tow bar the Nighthawk # RM-676 is the upgraded version of the Falcon All-Terrain # RM-522. It comes with safety cables, LED light for easy hookup or disconnect in the dark, and a 6-way to 7-way adapter cable included unlike the # RM-522. It also has a higher weight capacity at 8,000lbs versus the Falcon's 6,000lbs capacity. If you prefer the extra features then the Nighthawk is definitely the way to go. If you choose the Nighthawk you will not need the safety cables I recommended before.
