Greg,
You're right... I did some mental math adding up 8.4NAV, various electronic modules, vented/heated/power leather seats and the math worked out. Very interesting... FCA must have been losing money on 4500/5500 extended warranties. I'm only annoyed about a business that decides to stop selling something, but doesn't bother to turn off the ability to buy it. I'm good about it though. Where I bought my 2017 5500 Laramie, has two 2019 5500 Limiteds without beds for almost $84K each.
BTW, I have to purchase another Sirius Satellite car kit for my LRE. After I finished everything else, I went to install it, found the box, and a connector, but no kit. I have one receiver I bounce around between the man cave system and my Jeep. Anyhoo, thanks again for the interface. Should have it over the holidays and will post over on my LRE thread.
Cheers, Ron
