Greetings Harry!
Welcome to the world of Vintage Airstreaming!
There were only a limited number of Coleman air conditioners for which drip
pans were ever available, and that was several years ago according to my
understanding - - from what I have been able to learn, none of the current
model Coleman air conditioners are supported by Airstream with condesate
drain pans. I know neither of the Coleman air conditioners that I have on
my coaches had the option of drain pans. Living in the Mid-Mississippi
Valley, my air conditioners produce quite a bit of condesate that drains
down the sides - - on the Airstream is has posed no problem so long as I
keep the coach Walbernized (it was polished and Plasticoated by the Ruths
about three years ago) - - on the Argosy, it is a problem in that it
produces rust stains on the painted sides of the coach that must be polished
out each time the coach is waxed.
Good luck with your coach!
