Roadmaster Direct-Connect vs Crossbar-Style Base Plates for 2020 Jeep Wrangler Unlimited  

Expert Reply:

The main difference between the Roasmaster # RM-521453-5 (previously known as EZ5) and # RM-521453-4 (previously known as EZ4) base plate kits for your 2020 Jeep Wrangler Unlimited, is that the RM-521453-5 is a Direct-Connect style, meaning your motor-home mounted tow bar attaches directly to the base plate's removable arms, without the need for a crossbar. This is the easiest to connect and disconnect, and it also makes your tow-bar about 20 lbs lighter, so the # RM-521453-5 is your best option.

That being said, if you are using the Roadmaster Sterling RM-555 (discontinued), Stowmaster # RM-501 or Tracker # RM-020 tow bar, and/or the Guardian Rock Shield # RM-4000, or Tow Defender # RM-4700, you will need to use the Roadmaster # RM-521453-4, since those require the use of the crossbar and/or quick disconnects. While the Sterling All Terrain # RM-576 is compatible, the included EZ Hook cables will not work, so you will need a set of standard safety cables, like # RM-643, when using it in conjunction with the Cross-Bar style base plates.

I've included photos to show the difference between the Direct-Connect and Cross-Bar styles, as well as a link to our FAQ on Roadmaster base plate kits.
