Recommended Flat Towing Base Plate Kit for 2021 GMC Canyon
Question:
I would like to know what base plate I need for a 2021 GMC Canyon to connect to a Roadmaster Sterling All Terrain Tow Bar, RM-576. Also can you recommend a diode wiring kit, battery disconnect kit, and a supplemental brake system. My coach has air brakes. Thanks Gary!

Expert Reply:
I'd recommend a direct connect type base plate, like the Roadmaster # RM37VR. For a diode kit, I'd go with
part # RM-15267, and for an automatic battery disconnect, use # RM-766 from Roadmaster, which is compatible with gas engine equipped Canyon models with a single battery.
For a supplemental braking system I'd recommend the Demco Air Force One, part # SM99243. The beauty of a permanently mounted system like this is that it's always ready to use. Just connect the tow bar, plug in the wiring umbilical and air hose and off you go.
I've linked to install videos for the diode kit, the battery auto disconnect and the Air Force One braking system.
