New Beaver Owner-Welcome! I think you bought the best year Beaver; 2006 or 2007. We have a new to us 2005 Beaver Patriot Thunder Lexington (40'w/tag). In 2006, Beaver made some real improvements to the coach (relative to our 2005), so you got a good one! If yours is like ours, the radio is a Kenwood, and yes, they don't make an exact replacement, but you could just yank out the old and replace with any other make/model radio (Kenwood, Pioneer, etc).
