Gene Knisley started selling S&S as well as Pinner in 1967 while working full-time as a funeral director. While he had these vans built by Pinner for the Missouri contract, they were badged as MCC products. When Gene's plant (known by then as Stratus Specialty Vehicles) burned in 1990, he had some existing orders completed by Taylor and CRS Coach. While built by other manufacturers, they were still sold as Stratus products. Superior did this as well when they had some of their Pontiac and Buick products built by Armbruster over the years.
I sold Stratus products from April of 1991 through July of 1994. The Knisleys are back (still?) in business, selling new McCoy-Millers as well as new and used ambulances, busses, and medicars:
