Yes I am using the RVibrake Towed Battery Charger https://rvibrake.com/products/towed-battery-charger?variant=8804388741  I have received information from other KL owners that have somewhat automated the activation of the wiring kit so the fuse can stay inserted all the time.  As soon as the snow clears and I can get my coach out of the driveway, I'm going to do set mine up in a similar fashion.

This might be a little difficult to explain, but let me try.  The RVi charger has a line that runs from the coach to its charging module.  On a Freightliner chassis that line is ONLY hot when the engine is running.  It then runs to the RVi charger module that monitors the state of charge of the towed vehicle's battery, and adjusts the charging rate from the coach accordingly.  That module also has a diode in it so the towed vehicle's battery cannot backfeed through the module.  This is designed so the towed vehicle battery is not drawn down in case the coach batteries fail.

However this diode also can come into play with the Mopar wiring kit.  I am going to remove the kit's fused wire from the power distribution panel and attach it to the RVi wire between the coach and the RVi module.  This will allow the fuse to remain in the line at all times as it will only be activated when the towed is connected to the coach, and the coach's engine is running.  When the coach engine is shutdown there will be no power to the towed and the fused line in the toad will be deactived.

I will still need to use the switch in the center console, but if I'm just stopping for the night and not starting the Jeep, I can leave it in the up position over night.

I haven't personally tried the above yet, but hopefully will be able to in the coming week.  I'll report back on how my initial testing goes.

I have a new Cherokee with the modification installed.  When the Blue Ox tow plate is being installed, i am having the RVi charger unit also installed.  I'd be interested in hearing if the powering modification described worked as planned.

I have a 2017 Cherokee Trailhawk with the switch mod installed.  We also have a charge line from the Entegra and that seems to keep the battery fine.  My problem is once the toad is detached from the coach.  Something in the AF1 is killing my battery.  Hard to believe it is the brake light indicator (which is on randomly) but that appears to be the issue. 

Can't find any other reason for the dead battery.

I have a 2016 Cherokee, and just got the fix installed by the dealer. They insisted they didn't know anything about the issue; we even explained that we were shown by our sales person how to set it up to tow. After many calls to Jeep Corporate customer service, who then contacted the dealer and set up the service, it was installed at no cost to us.

When checking out at the dealer, the clerk said that he had seen several of these being installed there!

Warning, the battery on the car does die while in tow. We will now look at that issue.

We went through all the same routine from the dealership and even Jeep corporate.  We finally got our wiring harness installed and added a battery charger (powered through the #6 pin of the umbilical cord from the coach).  

So...  we're set up with an AirForce1 braking system and RoadMaster tow on our '17 Jeep Cherokee Limited.  The cost of all this and the aggravation not only in making sure we have all necessary components to tow but more so, in the steps required to hitch up and unhitch, make me regret selling our '98 Wrangler.  All we had to do to tow it was wire the lights/brakes and hook it up (using BlueOx).  Because of it's weight, we didn't need an auxiliary braking system...  hitching & unhitching was easy-peasy...

This is John Johnston, associate editor at Family Motor Coaching magazine. I contacted an official at Fiat Chrysler Automobiles (FCA) about the above questions. Apparently there was an internal misunderstanding at FCA regarding when the Jeep Customer Assistance Center would start taking questions about the wobble issue. But that has been straightened out, according to the FCA spokesman, and FCA product specialists are now available to take questions at (877) 426-5337. (877-IAMJEEP). As for what Jeep Cherokee owners are supposed to do until the modification is made, this is the Fiat Chrysler response: "All owners will receive updated instructions starting next month. These instructions supersede any previously communicated information -- including that which is currently in customer hands. FCA US apologizes for any inconvenience." I asked for clarification on when next month the updated instructions will be available. The FCA spokesman's response: Late February. "But be assured our supplier is indeed tooling up." If anyone calls the Jeep Customer Assistance Center about the wobble issue and finds that the FCA rep doesn't know what you're talking about, let me know, either by posting here or emailing me at jjohnston@fmca.com.

John, if you're still monitoring this topic could you perhaps contact the folks at FCA to see if they are still pursuing this issue with the latest Cherokees and Grand Cherokees? We bought a new '17 Grand Cherokee Trail Hawk last October and started towing it this past spring. We've had the wobble problem at least a half dozen times since. At first I thought we had developed a problem with our Allegro Bus until I started researching the problem. I'll try calling FCA Customer Assistance tomorrow.

Thanks for your help with this!

We just purchased a 2018 Jeep Cherokee Trail Hawk two weeks ago.  In the process of getting set up to have the tow bar plates and wiring installed we were told we needed to get the flat tow wiring kit.  Sure would have been nice for them to tell us when we bought the vehicle.  We even had the January 2017 FMCA magazine with us while checking out what could and could not be flat towed.  Some were a real pain having to pull fuses.  We decided on the Cherokee and now found out there is another costly step before we can tow.  If Jeep knows it's an issue why are they not installing the fix on the vehicles?  I've been reading thru all the comments and have not seen anyone address the 2018 model yet.

We have never received squat from Fiat (surprise??).  We did add the wiring harness and battery charger, go through 16 steps to prepare for tow and detach from tow (that's 16 times two).  Had we known of this issue, we would have gone with another vehicle or kept our '98 Wrangler...  This is on top of other issues with this Jeep and poor workmanship...  

 

Fiat has indeed bought Jeep and made it a...  uh, a fiatsco...  remember the K cars...?

 

Revisited.

Did you ever do this?   How did it turn out?   Does it work?
