So I placed my order 2/03. Got a call from my sales guy 2/10 and said that they could submit it that day if I removed the max tow package. I told him to move forward, and on 2/11 my order was accepted with a TPW of 3/21. The actual build didn’t happen until 4/06 with an estimate delivery date of 5/01 to the dealer.
Constraints are what they are right now. I don’t see the problem getting any better this year and maybe not until early 2024. So if I have to add an aftermarket trailer brake control to my rig so be it, but I didn’t want that to be the reason why my order didn’t go through. I think it is completely reasonable for GM to drop the diesel option in the future so I didn’t want to miss my opportunity.
I suspect that the max tow is holding up your order as long as your dealers has the allocation to place the order with GM- but your dealer should be able to provide you with those details, might need to push them. First question should be how many people are on the list before you. This should give you an idea of what the problem is- constraints or allocation.
