Do you mean cut off the existing plug and install a retrofit TT plug?

The adapter is molded as one unit so I wouldn't be able to change the
wire gage. I could cut off the 15 amp plug and install a TT plug like
suggested above. That way the 'original' cord/plug could remain intact.

Airstream must have used the 10-30 plug in in a 'non-standard' fashion.
Our manual says to hook into "electrical service that accepts the
three-prong grounded plug" and "Always make certain that the trailer
park service is 110-115 volt, not 220V". Seams like Airstream wired it
the same as a TT-30 but opted to use the 10-30 plug for some reason.

Agreed, I may just go this route to be safe.

I'm somewhat of a purist, so I was hoping that there just might be a

Lampert Hitch (long time WBCCI members) in Denver has them and replaced
the connector on my Yukon to match the trailer. Dr. J, you're a valuable
resource on this list, thanks for taking the time to respond!
