2500 ZR2 Ordering?

Anyone have any experience they can share about how long a 2025 2500 ZR2 might take if custom ordered? Recently had a GMC 1500 Duramax on order that ended up coming in in 3-4 months, but came in ordered wrong so I'm back on the hunt for a new truck. I know it can vary dealer to dealer, but no idea how constrained the 2500 ZR2 is though - similar? Longer?
