This is how the van looked when I first bought it. According to the seller, the van began as an ice cream van. It was then sold at an auction to an environmental testing company which used it to analyze mold in New Orleans after Hurricane Katrina. They downsized their laboratory and no longer needed such a huge van, so I bought it from them.
The van is a 2000 GMC Savana 3500 with a fiberglass high-top. The high-top gives the interior 6'4" of headroom.
The interior consisted of a black insulated floor cover, a red fiberglass high-top, and two bubble windows.
