Wiring outlets, inverter and shore power
Do Rvers use regular romex, or something more flexible? I plan to have separate outlets for inverter and shore, so I don't run something off battery unawarely. Can I open up the inverter and screw ...

Both 5-15P and 5-20P work fine in 5-20R
Why do you need 5-20P?
Exactly. Lug weight in both versions are identical and have the ability to carry the same load, the only difference being the 20 amp has one pin turned 90 degrees to prevent it from being plugged into a 15 amp circuit. Electrically the 20 amp version offers no advantage over the 15 amp.
As stated earlier, I want a 20A rated plug because my inverter can produce 16.7A continuous and has a NEMA 5-20R rated receptacle to deliver this current.
Just because both 15 and 20A plugs will fit in a 5-20R socket does not mean they are electrically equivalent. The prongs may well be the same dimensions and weight, but what about the body of the plug?
I have a short, 12 AWG extension cord with a molded-on 5-15P plug. The 12 AWG cord can handle 20A, but can the plug?
Maybe, but I'm thinking a NEMA 5-20P plug would be a safer bet.
