Expert Reply:

In order to flat-tow a 2016 Jeep Wrangler you'll need a flat-tow wiring harness and for this you have a few options. These options included a set of magnetic lights such as the Heavy Duty Magnetic Tow Lights part # TL21RK or diode wiring kit that uses the factory tail lights like the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56200.

The diodes are required because they stop the back flow of electricity so there isn't any damaged to the RV's tail lights. I recommend the Hopkins Custom Tail Light Wiring Kit because it's plug-n-play and comes with the 4-way plug you need.
