I ordered a 2022 Chevy duramax high country October 21st. The only way they would accept the order was if I dropped the high country deluxe option. I really wanted the rear view camera and the heads up display, but it wasn’t a deal breaker. It was scheduled for a build the week of December 6th. I got a vin the first of January. It is stuck in a code of 3800. I have quit asking the dealer because they don’t have a clue. I have tried calling dealers when I see a truck on there web site but they are sold with people waiting behind them. I just hope I get it buy April to pull my camper.
