I wish that were so--but the 30 amp shore power can be on either the high or low voltage side of a neutral.
Correct me if I am wrong, but on a 30 amp circuit, you have a HOT and a NEUTRAL. If the NEUTRAL loses connection (which is what happened to fry his stuff) you have NO CONNECTION. You can only have the 0v and 240v (or low voltage/high voltage) difference if you have both HOTs connected with no NEUTRAL.
Of course, if the pedestal is miswired (e.g. a HOT/NEUTRAL reverse) all bets are off.

On a 30 amp RV it may well work out the same way only now you and a neighbor share a "Neutral" (The neighbor may be some distance away) so either NOTHIGN works (That's safe) or you see the same thign happening to your RV when HIS A/C kicks in.
Question. If you and a neighbor are sharing a NEUTRAL, and you (or he) loses the NEUTRAL on a 30 amp system, what is the return path that allows the current to flow into your HOT wire at 240v (ish)?
