Gem of a vintage Ambassador Land Yacht. Professionally polished to a mirror-like shine. 80% original interior in great shape. This Airstream has clearly been well loved by its owners. I used it as a my vintage store so haven’t camped in it. Thus, not an expert on systems. Everything was verified to be in working condition when I bout it 2 years ago. Have original propane tanks, owner’s manuals and jacks. Am trying to find someone to check out the systems but hitting dead end locally. Will keep trying!
