If the trailer model normally comes with a hardwired 30 amp cord and your particular trailer has a detachable 50 amp cord, then it sounds like someone switched out the original cord.
Looking at the two 32ft mallard trailers online, neither shows and option for 50amps.
If you bought this new, I would definitely be suspicious of the dealer.
Personally, I would return the trailer and find another dealer.
Even if they didn't add the 50 amp cord, they should have identified the issue right away.
If the did add the cord, then they have shown themselves to be incompetent at best.

I think opnspaces nailed it. What I don't understand is how the appliances lasted as long as they did on 240 vac.
And with appliances fried, what caused the batteries to run down to the point of being unable to run the slides in?
Looking forward to the final analysis.

Assuming everything is fixed and you keep the RV insist on new batteries as discharged batteries have compromised life. And before you take the RV back spend half a day doing a complete PDI, and or hire an independent professional to check everything.

Except he never said any appliances were fried.
If I follow the symptoms as described, the fireplace issue seems it could be unrelated.
There’s a mystery in this somewhere. Not the least of which, if anyone found a place to hook the 4th wire (of a 50a RV) in a 120v breaker panel….

Quote:I'll bet the assembly line workers ran out of 30 amp cords and added a 50 amp instead because they had it on hand. The question is did they only connect one of the two hot wires (this would be good as it's 120v 30 amp). Or did they do some kind of bonehead move and twist the two hot leads together under one screw creating 240v (This would be bad).
This would not put 240V into trailer. It would be a direct short at the pedestel and immediatly trip the pedestel breaker even if not connected to trailer input.

I also think it's unlikely this happened IF the 50amp cord is detachable as the OP suggests. If that were the case, then the connection to the RV would have remained 30amp.
If the cord is detachable, then that suggests that both the port on the RV AND the cord were switched to 50amps.

Twisting the two hot wires together would be an immediate short at the pedestal. HOWEVER, if they hooked up the two hot wires to separate screws and left the neutral wire disconnected, you have a 240v circuit and lots of damage.

The OP stated the shore cord was connected at walk thru. SO, if so, and there WAS a miswire, then how did the 120 appliances operate during the walk thru?????????????????????????? The OP needs to respond if the dealer did a good walk thru and the OP SAW that the TV and Microwave and Roof AC operated. Me thinks that he has a BAD power converter and THAT caused the battery system to go dead except for solar and his 120 appliances still operate. On a 30 amp trailer which has a outside input and you plug in the shore cord a 50 amp cord will NOT connect to that 30 amp wall plug on the trailer. Different size and connections. Doug

During walk through it was connected to shore power and we did indeed turn on AC. But AC also worked while camping but presumably off solar. It was near perfect out so AC ran very very little.
The 50 amp shore line does plug in and the LED on the trailer and cord ultimates when plugged in. Presumably indicating that power has tracked from pedestal to trailer. At least to the outlet?
I have told the dealer to not make any repairs until they tell me what’s going on. The last I heard from the sales guy after his adamant “it’s 30 amp” was “apparently it is 50 amp”.
During walk through the tech, not sales guy was adamant that it was 50. If it wasn’t I would have backed out deal all together. We are taking trailer to phoenix this summer for two months for medical care and one AC won’t cut it.

^So it has 2 Air conditioners? If so then it most likely/assuredly IS a 50A panel in the camper.
And your batteries died because the converter was/is somehow not working.
Or some mystery?
