Thanks for the differential tip!
Good catch on the wheels. Dodge used these on trucks up to 10k GVWR, so I figure they're a good, strong choice for the Burb.
Around 98k when purchased. Pushing 110k now.
I don't see any LS or LT identifiers on the C pillar.
As for the decal, I'm not sure. However, YE9 appears on the build sheet, and it's equipped with most of the nicer options:
Higher-end 40/20/40 cloth seats
Six-way power drivers seat
Power mirrors, locks, windows
Rear Heat & A/C
Keyless Remote
"Deluxe Front Appearance Package" & chrome bumpers
Deep-tinted glass
Etc, etc...
