I've been watching the various build date threads for a few months now. I ordered mine 10/19. It was "built" sometime in December and then was supposed to be shipped early January. I now have a delivery date of 2/7, though it changed from 2/1, to 2/4, now to 2/7.
Watching other threads, I can assume that from the date of ordering, you have anywhere from a 3-5 month wait. Most seem to be right around 3 months from order to completion, but this was based off most orders I saw placed in the fall/early winter. With the next wave of this chip shortage, I expect things to delay a bit further.
Also labor forces are getting hit big with this more contagious omicron variant, so I expect that is not helping the situation for supply chains and manufacturing, let alone just transport.
There are some lucky folks, that seem to have been straight lined with 2.5 month wait times. People that have ordered after me have received their trucks, but I bet there are a few that ordered before me, still waiting as well. I probably took more time because my truck is loaded 402a as well.
