Looks like they made a 50 style layout in a passenger van. No tall cabinets so you still maintain views. It appears to have a quick release mount for a rear captains chair as well, but no mention of it in the ad.
I don't think Mikracer was selling his van. That was just a CL listing he found and posted. The van in his avatar is an RB; the one in the listing was an EB.
