Thank you for all of the details and the picture! Since you will be interchanging between flat towing the 2018 GMC Sierra 1500 and the 2015 Jeep JKU there are some parts that we can use interchangeably between the two. I will give you a list of parts and highlight what parts are for which vehicle:

2018 GMC Sierra 1500
Roadmaster Direct-Connect Base Plate Kit - # RM-3177-3
Hy-Power Diode Wiring Kit - # RM-152
Connector - # RM-910030-7
Bracket - # RM-910030-5
Automatic Battery Disconnect - # RM-766
Stop Light Switch - # RM-751463

2015 Jeep JKU
D-Ring Adapters - # RM-035-1 for 1" Thick D-Rings or # RM-035 for 3/4" Thick D-Rings
Combo Kit - # RM-9284-2 (for wiring and locks/cover for tow bar)
Bracket - # RM-910030-5

The Roadmaster Nighthawk All Terrain # RM-676 tow bar is rated for up to 8,000 lbs and comes with safety cables and a wiring umbilical that easily connects to the wiring kits that I recommended for each vehicle.

For a braking system I recommend the Roadmaster Even Brake # RM-9400 because you can easily transfer it between both vehicles. Since the Even Brake draws power via a cigarette-type outlet you will also need to install the 12 Volt Outlet Kit # RM-9332 in both vehicles to properly power this braking system. You also need to install the 2nd Vehicle Kit # RM-98400 on one of your vehicles to interchange which one you install it on.

A lot of flat towing setups might require the use of a high-low adapter to keep the tow bar level while towing a vehicle. I have linked a helpful article for you to reference to see if this applies to you. If it does then I have also linked our selection of adapters for you to filter through.

I have attached some videos for a few of the products for you to check out but you will also want to be sure to check the owner's manual for each vehicle and follow any specific instructions for flat towing.
