I happened to notice this Air Forums Classified Ad for a 66 Trade Wind. It sounds like the owners renovated this old trailer similar to a lot of us. I thought this might be a good place to link it for future reference.

Take a look at all the renovations these folks did. You can imagine the hours and hours of work involved, not to mention the dollars.
Vintage Trade Winds are a nice sized travel trailer in my view.
