See my comments under vendor review...
I ordered my RV-10 tail kit in October '21 with the requisite deposit. Clearly Vans was aware in October of the supply chain issues but their projected delivery was 4 months. At the beginning of March they requested the remainder because they were "making parts and will be crating in April". In April I received an email saying they were "making parts and will begin crating May 30 - i.e. June).
From the posts here, they KNEW in October '21 they were not delivering in 4 months because that was what they had been telling customers in July and in January of this year they were still not delivered.
I am presently waiting (July 2nd) on an update after I was told they were "quite confident" they would be starting crating May 30th. I have not heard anything to date and my wife, who is a retired consumer protection attorney, is beginning to wonder if Vans is having cash flow issues. At the time I reassured her Vans is a reputable and successful company.
Having run my own companies, now I am not so sure.
More to come as this process continues...
Update: Status says Assigned To Crating (6/2/2022). Given other comments here the obvious question is "what is still backordered".
