As with any Airstream project, it helps to be a double jointed contortionist that can work sideways, or up side down, while wearing bifocal glasses. I propped the couch up with a stick made to fit which I keep stored under the couch for any such occassions, pulled out the big drawer so I could sort of step/sit/straddle it instead of taking the couch out.
