Purchased white 24" x 32" shower pan with center drain and 2" skirts from Jazz Sales for $86.58 delivered on 6-30-10. Item # DF-243215521. 2" straight drain for 1" hose model # 308577 from West Marine. Dimension between the 80/20 structure is 32 1/4". Bottom of pan sits on top of Mercedes plywood floor. Added 1/2" thick spacer to van wall behind pan to keep it retained between front 80/20 and van wall. Cut 4" square hole in plywood floor and then cut a 3" square hole in the van corrugated metal floor. Popped four 7/8" dia. holes in the corners with a 1/2" conduit knockout. Used jig saw to cut between the holes. Fortunately I did a good job of locating the 1" OD SS tank inlet on the gray water tank. It all lined up as planned. 1" rubber hose drops down between the gray water tank and the Sprinter frame rail. Do not have a conventional trap. Gray water inlet is at bottom of tank equal distance from each end of tank. When there is water in the tank, the bottom of the hose will fill with water and act as a trap. TeamTexas had a problem with the tank contents backing up into the shower pan when he stopped. I do not expect that problem because my tank inlet is at the bottom below the wave and not at the end of the tank. We will see how mine works. If it does backup into the shower pan, I have a expandable rubber pipe testing plug with a wing nut that I can put in drain. It is shown in one of the pictures. Next step will be installing the 3/8" plywood shower walls.
