I am not sure who issues the feature availability charts but I have looked at them a few times and they are not totally correct. The code guides are the bible for car ordering and before on-line ordering, they were what dealers used to order from. They are reissued multiple times a year as stuff changes.
I would post one with the prices blocked out but the main page says this:

I have code guides going back several years for the Jeep GC. Until 2020 there was a package ADL, Skid Plates and it was available for the Summit but that package is gone for 2021. ADL are only in a group called AWY Off-Road Adventure II and this is only available on the Limited or Overland. The actual order process is all based on these 3 letter codes which date way back. So no skid plates for the Summit in 2021.
I looked at 2019, 2020 and 2021 CGs. I see no way a summit could (according to the data I have) be ordered with Quadra Drive II (AWB) or ELSD (DSF). Summit does have Quadra-Lift (SER) as standard.
I had a 2018 and 2019 and 2020 Trailhawk and all came standard with ELSD and Quadra-Drive II, verified on Monroney label and all had the V6.
Back when we ordered Chrysler lease vehicles on paper forms they printed out the code guides, put them in binders and you checked them out to take home and discuss with the wife. Then filled out the paper order and at work a Chrysler corporate sales person checked the form for errors and made sure you ordered what you wanted. It's complex. Once your order is in, it can't generally be cancelled and if you get the car and something you wanted is not there, too bad for you.
FCA lease is for FCA management or management retirees. It's a one payment per month that pays for everything but gas. New car every year, unlimited miles, plates and registration, insurance, loner car when in the shop and all maintenance.
I started at Chrysler in 1976 in Manufacturing Group IT, we did data center IT for all assembly and stamping plants. Big data center was at Outer Drive and Mt. Elliot in Detroit. Sales data center was in Highland Park MI and Parts Data Center was in Centerline MI. All 3 totally separate. All data centers merged during the Iacocca days. I spent time at all the assembly plants, several are no longer there, Newark DE, St Louis MO, Jefferson in Detroit, Dodge Truck and the wonderful Hamtramck plant built by the Dodge Brothers and Sterling Heights plant.
Assembly plants used to have IBM mainframe computers in the plant that ran the lines and printed out multi-colored broadcast sheets you would sometimes find stuffed under a seat or someplace. If the mainframe crashed, the whole plant stopped. This was very very bad. My group worked on software that ran the lines and other stuff there. Those were the days.
