[aprssig] slightly OT:recessed male twist and lock

[Wes Johnston]

Our state guard unit has a trailer (yes we use it for aprs), and the
power cord is a standard 20 or 30amp RV 3 pin plug pigtail hanging out
the trailer.  We end up adapting this to a twist and lock plug for our
generator.  Does anyone know of a MALE recessed mount twist and lock or
30amp RV plug we can use?  Ideally I'd like to mount it in a single gang
box on the tounge of the trailer to reduce cord clutter.  I do not want
to be forced to use a male to male plug for running power from the genset.

Some of us may remember the 15a male recessed mount connectors that old
VW campers used to use... we're looking for a higher current version of
the same sort of thing.
