The manufacture date sticker is almost illegible. I think it says 13-1201477 and November 1973. Almost a 1974.
This trailer is fundamentally sound. There have been some questionable PO mods. It would take some work to get it back to more or less original, but it is doable.
This trailer originally had a
furnace, (Coleman?). The exterior vent hole is quite tall and narrow. I don't think the PO changed the fibreglass at all, witch would make reinstalling the
furnace, if you can find one, much easier.
The original ice box has been replaced with a 120 VAC bar
fridge. The logo on the road side is intact. The install looks OK, if all you wanted was to camp close to a power bush, then it would do. I would put a12VDC compressor based
fridge there.
The dinette cushions were 8” memory foam. Good for sleeping. The front cushions seem to be recovered original cushions.
The corner reflectors, have been screwed in place.
The air conditioner vents out the bottom through a large hole cut in the fibreglass. I think it draws it's outside air from the gaucho and exhausts out the bottom. I could be wrong.
