30 AMP Connection at home
The owner's manual says that you need a 30amp connection in order to run the AC. Does this mean I would need to wire my house with a 30amp receptacle in order to operate the AC while prepping and ...

Well I stand corrected. Oups.
I saw and heard mistake where it was wired wrong and sent 240v in the rv appliance...
This is the big problem with a 50A circuit because this can happen. If the "service" neutral isn't connected, either through miswiring or a bad connection in the cable, then a heavy resistive load like an AC or water heater can cause the voltage of the neutral wire inside the RV to "move" toward that leg's voltage making the voltage of the other leg higher and sensitive stuff like electronics makes smoke.
That's why protection devices that can warn you, or better yet not connect the power to the RV, if the neutral is missing are so important.
That can happen to your nice 30A 120V campground pedestal too, if the open neutral is somewhere with the main campground feed. Granted, it's more likely to have a failure at your pedestal, in your power cord or transfer switch than the campground wiring but it happens.
It's is easier to reach higher incorrect voltages when you're the one pulling down on one side and just your site has the problem. The rest of the campground somewhat averages out both sides, even if the neutral were open.
