After a long search, I purchased a Argosy 26 this weekend. It amazing how much bigger it feels after owning a 20' Minuet. The storage, additional height and width are great.
PO had installed new axles and it has good paint with no body damage and everything works.
It has the original furnace so that will have to be replaced. I'm also going to purchase two new twin beds from a local manufacture that builds to fit for boats and RV's. However, if some one has a couple in good shape in the Seattle area I'd consider purchasing as opposed to spending the extra $.
It's a twin bed config but the owner said he purchased from the original owner and they bought it as a double but brought it back to Airstream after just a year and had them install the second twin. It also has a removable hanging bunk.
If anyone has a lead on the mattress, let me know.
