Hi John! Welcome to FiberglassRV, we're glad you're here.
Liberty Van Companion.. wow. Few of those around. Someone must have really loved you to pass it along to you.
I can't help with your questions though. I can point you to the Liberty album: Fiberglass RV - Historian's Album: Liberty
Here's a thread that started back in 2009 but just got updated too: http://www.fiberglassrv.com/forums/f...ler-37303.html
perhaps Dirk can assist with your questions.
