According to Roadmaster, their # RM-8700 Invisibrake supplemental braking system is fully compatible with the Mopar 82215382AB wiring harness. The wiring harness is going to utilize the Jeep's taillights to operate in conjunction with the motorhome's taillights, and would be a separate system that wouldn't have any impact on or affect the operation of the Invisibrake system. You'll also need to use the brake stoplight switch kit, part # RM-751490 in conjunction with the Invisibrake.

To flat tow your 2021 Jeep Wrangler you'll also need a tow bar, base plates, safety cables, and possibly a high/low adapter. If you do not already have these items then I have the following recommendations for you:

Tow Bar: Roadmaster Falcon All Terrain, Non-Binding Tow Bar 6,000lbs # RM-522. This tow bar features non-binding latches and a large hookup radius to make connecting/disconnecting on any terrain easy peasy.

Base Plate: Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521453-5. These direct-connect base plates make attaching to your tow bar quick and easy and have removable arms to provide a clean look when not in use.

Note: This kit is designed for factory steel or plastic bumpers, if you have an aftermarket bumper let me know and I can find the correct fit for that specific bumper.

Safety Cables: RoadMaster 68" Single Hook, Coiled Safety Cables - 6,000lbs # RM-643. The coiled design of these cables will help prevent them from dragging on the ground and being damaged.

To keep your tow bar level between your motorhome and Wrangler you may possibly need a high/low adapter. This does require some measuring on your part so I've attached our help guide article to walk you through the steps of determining the correct rise/drop needed.
