After owning several vintage Airstreams over the years, I Just bought my first Argosy...a '75 25 footer. Good news first, the trailer is all intact and original, straight on the outside with a need only for some paint on the curved panels, and original on the inide needing only cosmetics and cleaning...ie upholstery, drapes, etc.
Now...for the bad...
The trailer sat unattended for several years. It became a damn rat trap. I found a nest in the rear streetside locker near the inverter as there is a larger than necessary penetration for the plumbing coming in which allowed the critters entry. I found droppings everywhere, in all areas behind which one could not see. I vacumed and removed all droppings from every cubby hole/spot one could imagine and scrubbed with Simple Green.
Fine but...I cannot get the darn smell to diminish. So...do any of you have experience with odor removal? I am going to paint the floor areas/plywood in all accessible cubby holes which should help...but I welcome any thoughts or suggestions beyond that. I also have removed the flooring and all traces of hideous carpet in those undercabinet/cubby areas and of cours will secure the critters entry with some screening and covering.
