For sales is a 2013 Airstream Interstate (Lounge) one a 3500 Mercedes Benz (dually) chassis. Long wheelbase not extended body. 23.1' long with about 110,000 miles.
It was not in use for the past 2 years. Plane was to repair some rust issues which you see in the pictures and remove the propane system convert it to electric only and go from a lounge to a twin bed configuration. 
Unfortunately for me I got sick and could not finish the work. All part removed are available and stored in a storage unit. 
Wet bath is fully intact. Upper cabinets are intact as well as front seats. 
Has to be towed away. 
I have a full set of wheels with aluminum wheels. Lots of extra parts which I purchase for this modification will go with it including a Magnum hybrid inverter/charger.   
It was only used for long distance traveling which is favorable to the 3.0L V6 diesel engine with bluetech. 
Any questions please message me.
