Greetings to all.

I am writing to seek some advice regarding a future vehicle purchase. I am considering placing an order for a 2027 truck once they become available. Specifically, I am looking for a Silverado 1500 or a Sierra 1500 in a crew cab short bed configuration.
Currently, the specific features I want are available in certain models but are difficult to find in the inventory typically available on the lots. I am interested in ordering a vehicle with specific items that are often tied to package deals, such as a factory lift (no more than 2 inches), roof marker lamps, and power trailering mirrors.
I am wondering if anyone has experience ordering these types of less common items as standalone options rather than as part of a larger package.

Any advice or insight you can provide would be greatly appreciated.

Best regards,

Louis
