Final point....You never spoke with the engineer...Meaning you played the telephone message game...And what do we all know about that game? The message always changes....so realistically did the right question actually get asked to the engineer and did his precise answer make it back un changed? very unlikely.
What a tool... When you have a technical question and contact Mopar do you thing they transfer you to the engineer who designed that part of the Vehicle? I call C/S they did not have the direct answer, they took my number, then followed up with their technical team and then 2 days later called me back with the answer to my question that I have discussed here. Sorry that was not good enough for you, for me I take their word for it..
I would suggest you have equal or bigger issues, assuming that Gasser motorhome in the background of your picture is what you tow with, and considering you have many upgrades to your Rubicon including skids, your Wrangler exceeds the towing limitations of your RV. With that said it is clear safety is not a concern to you.
It is unfortunate some to not take these issues seriously.
