I would upgrade that extension cord to a 12ga.. Most "Contractor" cords are 14 or 16.

Good point, I did spring for a 12ga extension cord. I didn't like the price for a 50' cord, but what can ya do?

In Taylor, MI and several other places there is a store "Ollie's Bargains" and last time I visited they had, I think a 40 foot 12ga. CHEEP.

I also have a 100' 12 ga that I paid a whole lot more for.

I cut the 40 footer into two lengths, roughly 2/3 - 1/3 and used 20 amp plugs and outlets to finish it off, (Oh I cut like six inches off to make an adapter for use inside the RV)

now the short cord is 20/20 the long cord is 15/20 (Fifteen amp male plug original on the cord) and the adapter is a special 20-15 for a space heater here in the RV.. The cord feeds a PSRV inspired breakout box (Plug and socket) this has 15 amp pulg as well but if I ever replace it I'll go to 20.

The plug end of this break out feeds both the special socket and the REAR Air conditioner (I figure if I need heat I do not need A/C) this way I can pick up the extra 20 amps on a 30 amp site (Where I'm parked now)

The long cord will plug into either a 15 or 15/20 amp duplex. the short one 15/20 only I also have a pair of 15/20 outlets (Each on it's own dedicated circuit breaker and fed with 12ga wire) for space heaters. Work well, No aroma of hot insulation like I got when the heater was plugged into a standard RV outlet

What is the difference between a 15 amp outlet and a 15/20?

On the 15/20 the NEUTRAL slot is "T" shaped

On the 15 amp plug the two blades that count are parallel
on the 20 the NEUTRAL is turned 90 degrees.

And that is the difference.
