Our 31 also sat for 10 years due to chronic illness by the PO. She has lived in our back yard undergoing slow renovations of just about everything for the past two years.
Would we do it again or just buy a newer unit?
There are days when I really don't like having to do all of the work on this one when we could actually be USING it, but then there are days when I love that we know every inch of her. (the good, the bad and the ugly)
It's a choice only you, knowing your available time, energy and $$, can make, but you either way, you are a member of the Airstream family!
