For flat towing your 2020 Jeep Wrangler behind your 2021 Tiffin Allegro Bus the following items are correct:

1. etrailer SD Non-Binding Tow Bar - RV Mount - 2" Hitch - 6,000 lbs Item # e34ZR
2. etrailer Invisible Base Plate Kit - Removable Arms Item # e98948
3. Demco SBS Air Force One Supplemental Braking System for Motor Homes with Air Brakes - Proportional
Item # SM99243
4. Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit Item # RM-15267

I recommend adding a Roadmaster Battery Charge Line Kit for Towed Vehicles Item # RM-156-25. This line is a simple hook up from the positive post on your Jeep battery down to the S pin on your 6 pole plug. Since the braking system requires uses of the Jeep battery for power, it is drawing power from the battery each time the brakes are applied. With the charge line, your RV trickle charges your battery on your Jeep while it is being flat towed so it is ready to go when you get to your destination.

I have include links to videos to help walk you through the instillation process on each item. The instillation for the braking system is on a 2016 Jeep Wrangler and is going to be the same as far as the wiring however, instillation location of the main unit is optional.
The instillation of the diode kit is on a 2014 and is going to be the same with the exception of the wire colors behind the taillights. The wires may be different color and would require testing to determine the correct wires needed for the diodes.
The battery charge line is on a 2015 Jeep Wrangler and the instillation is going to be the same.
The base plate and tow bar are both on 2020 Jeep Wranglers.
