Question:
So I have a crossbar that fits our 2018 Cherokee and accepted our Guardian shield. We now own a 2024 Wrangler 4xe with the factory plastic bumper and want to use our crossbar so we can use the Guardian Shield. Is there a baseplate for our Wrangler that will allow this? I've been told that the Wrangler bumper is too thick and will not allow the use of a crossbar.

Hey John congrats on the new Jeep! There's definitely a crossbar baseplate designed for the 2024 Jeep Wrangler 4xe that will work with your current set up. It is the Roadmaster item # RM-521453-4. This crossbar baseplate has been used on Jeep Wranglers for 6 years now so no worries about the bumper so long as it's the factory plastic or steel one.
I have linked an installation video below along with the instructions so you can see how to get this baseplate set up.
Here are the rest of the parts you'll need to flat tow your 2024 Jeep Wrangler 4xe:
Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes
Wiring Harness - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267 or item # RM63MR if you have the ParkSense proximity sensors

Hey John, how did things go with the Roadmaster baseplate on your Wrangler 4xe? Did it fit well with your existing crossbar and Guardian Shield setup? Your update could make it easier for others working with the factory plastic bumper.
