The plug is outside right where the RV is. There is another duplex 20amp set of outlets nearby. The only time I'll need to meet code is if the house is inspected for some reason like selling it. Then I'll just swap it back out.

I didn't want to use an adaptor because it was just one more connection. The way I have it looks just like an RV pedestal, waterproof and all.

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 90 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 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 I just have to make up an exterior box with 50A, 30A, and 15A and wire it up

Well, Booster, that Marinco 30 to 15 adaptor showed up this evening (Amazon is amazing!) and is exactly what I was looking for.

Very compact, gives me a way to plug in should the rare need arise, and I can leave the 30A cord at home.

Thanks for the link!
