Hello Thad,

Happy to get you the parts needed to flat tow your 2014 Jeep Wrangler behind your RV so you can be on the road to adventure!

Here is the complete package you will need (I am including the parts you already have):

- Base Plate: Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521448-5

- Tow Bar: Roadmaster Nighthawk All-Terrain Tow Bar w/ LED Lights - Non-Binding - RV Mount - 8,000 lbs # RM-676

- Wiring: Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152
*If the tow bars did not come with the 6 way for the front of the Jeep, you will also need: Vehicle End # RM-910030-7 and Bracket # RM-910030-5. I attached a wiring diagram so you now how to wire it up.

- Battery Disconnect: Please ignore the title, I have confirmed with Roadmaster that this is the correct one, it does not only work on diesel engines. I am currently in the process of trying to get this fixed. Roadmaster Battery Disconnect for Towed Vehicle w/ Flat Tow Brake System # RM93MR, if you would prefer one with key fobs # RM39ZT

- Brake Light Switch: *If the brake lights do not work with the towed vehicle's ignition key turned to the "tow" position, you need a brake light switch kit to provide a signal to the supplemental braking system. Then you will need RoadMaster Stop Light Switch Kit # RM-751452

- Charge Line Kit: I like to call this part "Peace of Mind" as it will make sure that you do not have a dead battery when getting to your destination, the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25

- Braking System: If your coach has air brakes- Demco Air Force One Flat Tow Brake System for RVs w/ Air Brakes - Wireless Monitoring - Proportional # DM26VR. For Hydraulic brakes- Demco Stay-IN-Play Duo Braking System for RVs w/ Hydraulic Brakes - Wireless Monitor - Proportional # DM86VR

Most likely you will need a high low adapter to get you to level towing, I attached an image of where the base plate will install. On level ground, if you could please supply me with the measurement from the ground to where the baseplate will install, then on the coach side also on level ground, from the ground to the inside top portion of the receiver. Once I get that from you I can find the right one for you.

I also attached a great help article on the "Must-Have Flat Towing Components," it is a great read for someone who is new to flat towing, or a great refresher for the seasoned flat tower.

Are you new to flat towing, or just getting a new vehicle set-up? Where are you headed for the first trip after you get everything installed?

Thad, I like our roadmaster baseplate and I installed the roadmaster brake master system for our 2013 jeep. Our diesel pusher motorhome has airbrakes and it works well with it.
