Question Flat tow my 2017 Trailhawk

What else do I need? Here is what I have so far.
I am going to flat tow my 2017 Cherokee Trailhawk behind my motor home. I have installed the Blue OX base plates and a Hopkins wiring harness for the tail and brake lights. Will take it to dealer and have the Mopar 68321424 AB Flat Tow Kit installed for the death wobble Not sure yet what breaking system I will use. However I have run a wire from the AUX 12 volt in 7 wire to 6 wire connector up to the area of the battery. Do I need some sort of battery charger to keep the battery from running down while towing. I have been told that the Mopar Flat tow Kit uses the battery while towing to prevent the Death Wobble and that the battery will run down if not charged by the motor home while towing. What else do I need.

Mel,
I am having my 19 Trailhawk outfitted with a Roadmaster base plate, Falcon All Terrain bars and the Invisibrake. The Invisibrake charges your bat while towing.
The dealer suggested The Roadmaster products and I like the idea of the invisbrake installed one and done

I mispoke on the Invisbrake charging the battery. My dealers install guy adds a charge line from coach to toad battery on every install he does

Well I bought and installed the Blue Ox base plates, A new Hopkins wiring Kit for the tail and brake lights. I bought a used Blue Ox Aladdin 7500 lb tow bar I bought a new RVi brake battery charger, and a used Hopkins Brake Buddy, and misc wiring and switches. My total cost for everything was about $1200 I detailed it all on my website.

It is still the same for the harness alone. It cost me $200 labor for the installation with tax shop supplies and the harness the total was $365 If I had known what I know now I would have installed it myself.

Just installed my Invisibrake, and yes, it does charge the battery. One of the reasons I went with it over some of the others. Details here:

Make sure your 7 pin connector has a “hot” 12 volt pin ( #4 ). Mine had no power to it.

Might be what my install guy called a charge line?

Guys - the Invisibrake has a built-in trickle charge feature when operating. All you have to do is remember to turn on the motorhome's parking lights when towing. Check out page 4, item #3 here: https://www.roadmasterinc.com/pdf/85-4737.pdf
