I went to the dealer for the first oil change and had them program the side mirror to tilt when in reverse. Based on what I have read, the tilt mirror option is for the passenger side only. Well, it works on both mirrors. Was I mistaken on what I have read or or did I just a good dealer??

Dealer good. That other Jeep forum site, bad.

I had mine done too... It wasn't where the other forum said though
“Auto tilt in reverse" for the side mirrors feature programmed/implemented.
• Here are the DRB directions (Thanks Milous):
1. Go to the FCM screen
2. Select "ECU Details"
3. Select "Misc Options"
4. Mirror tilt function is at the bottom of the list

yes both mirrors tilt.
