the 30 and 50 amp statements here seem to me to indicate a possibility of mfr. error?
Doubtful ... I suspect quite a bit of this confusion is on the part of the OP. First, 50 amp service which he claims his particular trailer has is a Zinger
option that includes 2nd A/C prep according to this
Zinger Features Page. Since the OP previously referred to his trailer as having a "huge 50 amp cord" and that he's is using a 30 amp > 50 amp dogbone so he can plug into the campsite 30 amp service that would suggest his particular trailer is indeed wired with 50 amp main service, the question being whether he understands that 50 amp RV service is really 100 amps - i.e. 50 amps across each of
two legs. Plugged into 30 amp campsite service using a dogbone, both sides of that 50 amp service at the trailer end would normally be powered. Considering he's lost most of his 120 vac except the microwave oven that in turn would suggest that one side of his incoming 50 amp service wiring is dead while the other leg is still hot. That would explain why the microwave still functions but no other 120 vac devices do. If the converter itself is on the dead side of those two incoming legs that would also explain why it's not functioning either. It's difficult to tell for sure without actually being there to analyze but my suspicion is that just one side of his 50 amp incoming service has a problem and the converter itself may be fine ... maybe. The solution is to have a qualified tech take a look rather than rely on wild guesses from all of us who aren't there to actually look at the situation.
