I would really appreciate you sending me these pictures, thanks in advance...I can PM you some photos of the hitch work if you like. I removed the stock muffler and put in a Flowmaster 40 (just behind the resonator) and a Flowmaster American Thunder axle back pipe. This made the hitch strengthening easier, added more ground clearance and sounds better.
I have been towing a Airsteam Basecamp with a 2019 JL Rubicon and a weight distribution hitch with sway control, I installed a Hellwig rear sway bar on the Jeep and it's a night n day difference stability at Hwy speeds, I highly recommend this accessory for the JL.
I think beefing up the factory hitch can't hurt.
