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