@Peter9525 I don’t know if it’s the best way, but I use https://www.gmfleetorderguide.com/dmdindex.htm. Select the Year in the left column, then “Ordering Information” in the right column. On the next page, click on the Brand (ie: Chevy Truck, GMC). On the next page, select the Model from the drop-down menu in the upper right. Click “Distribution Updates” then “Full model year” in the popup. It’ll give you a week-by-week list of updates to the guide.
The other thing you can do is from the page before the pop-up, go through the categories to find a feature (for example, the Max Tow package can be found under Mechanical). The third column will have some notes with a number preceding them, any constraints should be listed there.
It’s not the easiest thing to sort out, it involves a bunch of manual investigation, and isn’t a guarantee.
I wonder about your dealer, though – they should be able to tell you why the order is stuck. When I ordered my truck, my dealer told me what constraints were holding it up, and we adjusted the order to compensate (we removed the multi-pro tailgate, which is on constraint for SLT and below models).
