Here's some pics from today... Had to change out my water filter canister but that's a whole different matter....
So here's pics of the cold air duct from furnace to the back of the stairs
Home depot or Lowes or any building centre should have a 4" flex tube and the fittings.. I had to remove two of the heat ducts to access the cold air intake. It's just like a vent cover but the 4" round duct catches most of it. Figured pulling a little cold from basement was ok. The pics of the heat ducts show the small tab which you turn to match cutout on furnace to release them.
I did this mod 2-3 years ago so the adhesive on the stick on 4"duct adapter is pretty good. I used a jig saw to cut the hole in the hardboard I used to block off the back of the steps. I put reflectix on the inside to insulate it a bit
It was an afternoon job if I remember
I also moved the rear basement wall to rear of trailer about 4 inches for more storage.
Just moved the backing 1x2 and the clips holding the pex water lines going to the low point drains on door side.
It was worth the effort for us!
