Question:

Hi Jon G answered couple of my questions, but I have more. 2020 Thor Challenger 37TB flat towing a 2019 F150 crew cab 4x4 5.0l My pick: etrailer Invisible Base Plate Kit - Removable Arms Item # e86YR Blue Ox Avail Non-Binding Tow Bar - Motorhome Mount - 2inch Hitch - 10,000 lbs Item # BX7420 Roadmaster High-Low Adapter for Tow Bars - 2inch Hitches - 6inch Rise/ - 10K GTW, 400 lbs TW Item # RM-048-6 Jon G list of recommended parts to complete the system: Flexo-Coil Wiring Kit - # RM-15267 Charge Line Kit - # RM-156-25 Roadmaster InvisiBrake Supplemental Braking System - # RM-8700 Stop Light Switch Kit - # RM89ZR Brake-Lite Relay Kit - # RM-88400 Questions: 1. Watching the videos for different products for the braking system, I think I prefer Demco SBS Stay-IN-Play DUO. if I pick this, do I still need to purchase the brake relay kit # RM-88400? 2. Do i still need to get the Stop Light Switch Kit - # RM89ZR? 3. I assume I still need to get both the Flexo-Coil Wiring Kit - # RM-15267 and Charge Line Kit - # RM-156-25 to complete the system. Is that correct? 4. Is there any other items I miss? safety cables, locks, pins, etc.? Thank you

I'm happy to help you get your 2019 Ford F-150 ready to flat tow! The Stay-IN-Play DUO braking system is another excellent choice and by going that route you won't need the Stop Light Switch Kit # RM89ZR but you will still need the Relay Kit # RM-88400 to keep the brake light signal on your F-150 from overriding the turn signal from the RV when you're applying the brakes during a turn. With the parts listed out here is the bare minimum that you need:

etrailer Invisible Base Plate Kit - # e86YR
Adapter Kit - # DM9523127 (for the base plate kit and tow bar to work together)
Blue Ox Avail Non-Binding Tow Bar - # BX7420 (comes with safety cables)
Roadmaster High-Low Adapter - # RM-048-6
Flexo-Coil Wiring Kit - # RM-15267
Charge Line Kit - # RM-156-25 (you want this to keep your F-150 battery charged)
Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor - # DM86VR
Roadmaster Brake-Lite Relay Kit - # RM-88400

When it comes to extras that aren't "necessary" I recommend the Blue Ox Tow Bar Cover # BX88309 to help keep your tow bar out of the elements and the Lock Kit # BX88101 to lock your tow bar to the RV and your F-150. I also recommend checking out the Blue Ox KarGard Towed Vehicle Protector # BX8870 which helps to deflect any debris that might be kicked up behind your motorhome.
