The Terry Classic page shows "Dealer Stock" on both the V21 and V22, which usually means those models are no longer in production. For clarification, you should call Heartland Customer Service at 877-262-8032 / 574-262-8030. Ask for Terry Classic Sales. They can tell you what's going on.
Popa - Dan's observation here is spot on. Terry Classis is no longer in production. That said, there are a couple hundred on dealer lots and there is a vibrant and growing community of Terry Classic owners on Facebook - link.
Buy with confidence as new Terry Classics on dealer lots continue to be backed and supported by Heartland RVs and the full unit warranty.
