Expert Reply:

Yes, we can help you put together a complete package to flat-tow your 2018 Jeep JL Wrangler.

You will need:

- Base plate kit
- Tow bar
- Flat-tow wiring harness
- Safety cables
- Supplemental braking system
- *Possibly a high-low adapter.

Please links for each item below:

Base plate kit, I suggest etrailer Invisible Base Plate Kit - Removable Arms, # e98948. This is a confirmed fit for your 2018 Jeep JL Wrangler. With this you get a clean, factory look for your car when it's not being towed by using these invisible base plates. Tabs remain on tow bar arms and easily secure to base plate receivers with a quick turn. Simple, bolt-on installation with included hardware. Please note the installation video showing installed on a 2020 model Jeep.

For your tow bar, I suggest the etrailer XHD Non-Binding Tow Bar - RV Mount - 2" Hitch - 10,500 lbs., # e94ZR. This will allow you to flat tow your vehicle with the hitch-mounted etrailer XHD tow bar. The independent, self-supporting arms won't fall to the ground when unfolded, and smooth operation allows for easy hookup and disconnect, even on unlevel ground. Built-in rise/drop.

For the needed wiring I suggest the Roadmaster Universal Hy-Power Diode Wiring Kit, # RM-152. This diode kit allows you to use your vehicle's tail lights and wiring system while preventing feedback from your RV. Wires 2-wire and 3-wire systems to operate as a combined lighting systems. You will also need the Roadmaster Stop Light Switch Kit, # RM-751490. There is an attached video showing step-by-step installation of both of these items.

My recommendation for supplemental braking is the Demco SBS Stay-IN-Play DUO Supplemental Braking System - Proportional, # SM99251. This too is a confirmed fit for your 2018 Jeep Wrangler JL. It is a proportional braking system that never has to be removed, replaced, or reset. The DUO activates when your RV's brake lights go on and an inertia sensor in the towed car detects deceleration.

You have the option of leaving the tow bar attached to the motorhome while not in tow, if you choose to you may want cover it with the Roadmaster Tow Bar Cover, # RM-055-3.

And finally, you may/may not require the use of a high-low adapter. I have attached a link to a help article "HOW TO CHOOSE A HIGH-LOW ADAPTER" to assist you in making this determination. To flat tow your vehicle behind your RV the tow bar adapter is used to raise or lower the height of the tow bar to the "Safe Zone". The "Safe Zone" for a motor-home-mounted tow bar ranges from 3" above level to 3" below level. A tow bar adapter will provide the necessary rise/drop to get into the "Safe Zone". Discover this by measuring from the ground to the center of the base plate kit on your 2018 Jeep Wrangler JL and compare that to the measurement from the ground to the top of the inside edge of the hitch on your motorhome. If this distance is not within 3" of one another then you want to use a high-low adapter. Please note the link to a selection of adaptors attached.

Several product review and installation videos of the items discussed here have been linked. I hope they are of value to you and can provide the needed information. Please let us know what other assistance we can provide. Happy Camping.
