Roadtrek 190 and 210 chassis

In thinking about Roadtrek 190s and 210s because I find no other options that will fit into my garage with the nine foot door, I got to wondering: how much longer will Chevy make those van chassis? I did a search of dealer inventories of all the Chevy dealers within a pretty good range from my home and was rather shocked to see how few of these 2500 and 3500 vans are shown in inventory. Once, they along with their Dodge and Ford counterparts were the gold standard for service and construction vans.

Has anyone read anything about Chevrolet keeping on producing these vans?
