easy enough to make one- I have.
this demands common sense on the part of the owner- don;t try to run the microwave and the a/c at the same time...
with a 15A supply I know that I can run all the 12 volt stuff and the dometic 3 way on ac...and the a/c on a low fan setting.
if you overload- you'll pop the breaker on the house supply.
starting with an extension cord of the desired length w/ std "Edison" plug, lop off the female end.
wire into a Hubbell 30A female plug ( home depot)- the large spade with the 90º is ground ( green wire), the smallest spade is +( black) and the remaining is neutral ( white).
the Hubbell also makes other sizes...a 20A won;t match up...it has to be 30A for the spades and the lock tang to line up.
at some point I will wire up an outside box- I have no pressing need so it's on the to-do eventually list- the rv pad is adjacent to the laundry room with has unused 50A dryer power...so I just have to make up an exterior box with 50A, 30A, and 15A and wire it up
