Almost exactly my build (we spec’ed the hitch) and shifts in EDD. I know EDD doesn’t mean much, but having it disappear completely isn’t confidence inspiring.Model Y LR, White, Black & White, 19", five seats, no hitch, Massachusetts.
Ordered Tuesday July 13 with a projected October delivery; one day later the website presented a window of September 12 - September 30. Yesterday (7/23) dates changed to September 06 - September 26. Today the dates disappeared.
Seems like this isn't uncommon.
