That's going back a ways, but I had an 89 Holiday Rambler Imperial that had basements, so they've been around for a while. Couldn't tell you the exact lineup back then, but roughly (and I could be completely wrong) they had the 2000, Monitor, Vacationer, Endeavor, Imperial and Crown Imperial. I'm probably missing some. Not sure about the Vacationer and Endeavor. NADA doesn't even list some of these.
