Thanks, folks. Always quick and knowledgable responses here! Glad to hear I may be in luck. Putting the 30A plug back on is a no-go, as I literally cut it off, since my power center is dead that it was hardwired to. Not to mention it's incompatible with the inverter setup I have now. Good to know about the adaptors, and I've seen inline surge protectors- I may look at getting one of these so I don't get anything zapped. It sounds like an inline 20A breaker would be a good idea. If I can find one that happens to have handy 3-prong outlets in/out (male/female), that would be perfect...
The 12GA cord I'm using is rated for 1875w, and the AC draws 1600w at full tilt. It would be switched over to fan-only (120w) or turned off to briefly run the microwave (1000w) or coffee maker (650w), but the tiny TV sips on DC power and the fridge would be running off propane. Seems perfectly doable as I've designed, unless I've missed something. This isn't a giant Class-A or anything. :) Just need the basics going here and there.
