Reworked the gray plumbing on the A124 so the sink and shower are now hooked to a standard 3" sewer hook for use at campgrounds with sewer connections. Can also still use the aqua container for sites that are only electric and water. The sewer hose is stored in a vinyl 5"x5" white fence post attached to the rear bumper. The sewer hose and all attachments fit in the fence post.
