2010 Aliner Expedition Day 2: More Demo, Corner Floor Repair & Cleaning

We made it to day 2 of demo & cleaning only to discover additional damage (looking at the wall we assumed it was there). Our biggest challenge has been finding seals or windows locally. It looks as though most of the items have to be ordered which is frustrating when working with a short remodel timeline. We were able to pick up the following items in town for the demo so at least we can continue progress:
Home Depot
4x8 1/2” PVC Sheet (For the wall)
(2) 1x2 PVC trim (For framing seat)
(2) HD Straps (To Secure Floor)
Box of wood to metal tap screws
Harbor Freight
HD Rivet Gun
Assorted Aluminum Rivets
