2018 Touring (🍁) - Deep Scarlet Pearl
If you have just the one trailer or don't mind moving the equipment between different trailers why not go the Bluetooth route!
I can see it now - "No officer, I wasn't using my smartphone, I was using my trailer brakes." >
Looking at controllers myself, but will probably go with Redarc for the compact permanent install. There seems to be an updated version available in Australia (v3), not in North America yet.
