22 Summit….air suspension however is back on the build sheet
I ordered a SR on 10/21, and my dealer confirmed me the eLSD was a required delete on the standard Summit at the time. The build sheets I've looked at for the vehicles which have eLSD deletes show a 195mm "conventional" rear axle, which doesn't imply any sort of LSD to me. The question I would ask your dealer is, at what point did they become aware of the required delete? It could have been a mistake, but it does raise the question in my mind.
One important thing to check, if your configuration preview doesn't have a OID, then I would find a different dealership. If you ordered it before me, then it should also have a VIN by now. The reason I mention this is because there have been some less reputable dealers out there saying that they will order your vehicle, but in reality are waiting for an already ordered one or looking for a nearby similar one to to try and sell you instead.
