Hey Dave,
I have the following flat towing component recommendations for your 2024 Jeep Grand Cherokee Overland:
Baseplate: Roadmaster Direct-Connect Base Plate Kit # RM77ZR.
Tow Bar: etrailer XHD Non-Binding Tow Bar # e84ZR. This tow bar comes with safety cables bracketed to the arms so that you don't have to purchase them separately or worry about them dragging. The head/shank has a built in drop/rise to help keep the tow bar level without also purchasing a high/low adapter. There's also a bar to hold up your excess 7-way cable so it won't drag on the ground.
You're right on the border of weight capacities so I went with the higher capacity # e84ZR. If you go get your Jeep weighed while fully loaded like you'd be if you were travelling and fall under 6,000lbs you could switch to the lower capacity # e74ZR and save a bit of money.
Tow Bar Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This kit will transfer your light signals from the motorhome to the Jeep and also transfer a charge over to the Jeep battery if you have a charge line installed. If you have ParkSense proximity sensors then you'll need to switch to the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage LED Tail Lights # RM63MR instead.
Braking System: If your 2018 Tiffin Phaeton has hydraulic disc brakes you'll want to go with the Demco Stay-IN-Play Duo # SM99251. This will need to tap into the brake light switch, which isn't useable in your Jeep so you'll need to also install a RoadMaster Stop Light Switch Kit # RM77RR to send the brake signal to the indicator light of this system.
If your motorhome has air brakes then you'll want to go with the Demco Air Force One # SM99243 instead. This uses a reed switch instead of the brake light switch so you would not need a stop light switch kit with this system.
Since the battery will drain while you tow I recommend also installing a charge line kit # RM-156-25 to avoid having it die while out on the road. If your motorhome doesn't have a charge line ran to the 7-way then you'll also need part # RM-156-75.
If you have any other questions just let me know and I'd be happy to help.
