I don't know about 2005, but I do know from vintage Airstreams it is not just unscrewing a few screws. The cabinetry may need disassembly. How about a couple of vertical supports that would compliment the Airstream design like square aluminum tubing? There are also TV mounts that are attached to the ceiling (you would need to find a rib).
Sail on silver girl. Sail on by. Your time has come to shine.
