2020 Airstream Bambi 22FB TT
Bluetooth backup camera.
Replaced the standard pressboard tabletop with a custom made butcher block top. 
Replaced the accordion shower door with a custom retractable self-cleaning door which is more attractive and efficient.
Better than new.  Took the Airstream to Colorado and had such a great time, we decided to buy a place there.  2,000 miles on trailer.
