I was at my dealer last weekend and my Black Diamond Edition was at 3300 with TPW of 9/27. I believe a few others with the same trim/package have the same TPW. My experience with chat has matched what the dealer is telling me so far. I'll check chat again in the morning to see what they say.It's a black diamond duramax, I think that is only available in duramax but it's got everything except snow prep and illumination pack.
The dealer is also the self proclaimed "largest sierra volume dealer in the states" so allocation shouldn't be an issue. It's at 3000 according to the sales manager last week when it still had the 10/4 date. Maybe i just got bad info from chat. Maybe it's legit. I know supply chains are all a mess right now.
I'll probably dm usmarine the first week in oct to try to get some legit info. Been trying not to bother him with it until it's due date came closer.
