Question:
I have a diesel pusher motorhome with air brakes, will the Roadmaster Invisibrake RM-8700 work on a 2019 GMC Canyon? I dont want to plumb my coach for an air port to attach to the Canyon

Expert Reply:
The Roadmaster # RM-8700 Invisibrake would indeed be compatible with the air brake system on your motorhome, as the braking system is activated electrically via the brake lamp signal from the motorhome.
The invisibrake isn't a vehicle-specific item, it'll work great with your GMC Canyon as you can see in the linked installation video.
