What years had alum. 120V wiring - did 1969?

We're considering buying a 69 Globetrotter. I know that some of the later-60s trailers (for example, most Caravels) had Al wire for the 120V circuits. I heard on the VAP that it was late-67 and some of 68, but I've also been told it's more extensive than that.

Does anyone know if this carried over to the later post-69 trailer design?

Thanks

The 69 may have it as it was used in house wring into the 70's. There is nothing wrong with the wire it's the connections that cause trouble. I changed out my plugs in the 67, with Al compatible plugs and used contact grease on the connections and have no trouble with my wiring. I would not be afraid to buy a trailer with Al wire, in fact I would use the fact to get the price reduced .
I would love to have a 69 Globetrotter, not many of those short wide trailers around.

For what I remember,
AL wire was used in 66-67-68 for 120 volt.
CO wire was for 12 volt.
Rumor has it, there was a CO shortage due to the war.

Interesting, I would have expected it to be used more than that. It was in other TT's and mobile homes, and of course it was a number of years before they discovered all the associated problems.
