His is a Canadian build and he is a retired Jeep employee.I now recall you saying that you ordered yours on the same day that I ordered mine and thought it was odd that you could order the eLSD. I'm wondering if that is playing a role in your production date? I would be surprised if the rear entertainment is the issue as I would think that the rear entertainment system is likely to be installed by a separate contractor rather than on the production line (similar to the running boards).
EDIT: Just re-read Jake22's comment and it sounds like he has the eLSD so that would suggest that the eLSD is not the issue.
