The bathroom lavatory sink and shower join to drain down to the first (forward) tandem grey tan.
First checking the fit of all parts before they are attached/glued together permanently
Adding gray tanks to our vintage Airstream for the first time in 58 years!
During travel, trailers move and flex. While it is not legal or safe to ride in a moving trailer, someday I'd like to get a video set up to see the movement that happens. The movement can break areas that are too stiff. To be sure that our tandem tanks maintain a secure and dry connection, a flexible link is added between grey the two tanks. Thick rigid foam insulation is added to further protect the link and will keep the tanks from shifting forward and backward within the frame. A similar link will be added to the tandem fresh water tanks.
From the back of the rear grey tank, the used water will exit the trailer through the combination black and gray water valve. Unlike modern trailers, the dump valve will not hang below the belly pan. I just realized I have very few photos showing our dump valve - just not photogenic! Because in 1955 we had no dump valve, our Flying Cloud valve handle will not show on the exterior of the trailer. The valve handle will be accessible through a hatch in the belly pan. This decision will also keep our restoration with the beautiful clean design of 1955.
Both the fresh & grey water tanks with plumbing connections.
The portions of the frame that are cut out for the plumbing connections - all will be strong! Each cross member will be strengthened at the bottom with a heavy steel bolt-on bridge. The bolts will allow access to the plumbing if needed at a later date.
The shower pan's drain trap will fit inside the frame, hidden by the belly pan.
