I have a Chinook Concourse 2004 that I keep in storage near SeaTac Airport in Seattle. I have only had it a few months...the grey and black tanks were flushed.. just figured out where the bypass valves and drains are for tanks. Question for Seattle Area folks... Can I wait until the first week or two of this Dec to winterize with antifreeze? Hope to use it around Dec 10th for a few days. Thoughts on moving it south for winter to avoid having to winterize? Have a son in Tucson and friends in Phoenix.. Thanks
