If you do not have a battery in the trailer, start there.
If your battery was stolen, and the wires left touching the frame, that probably caused the $350 converter to start sparking.
Look for a replacement here.

Camping without a battery. That can also fry the converter. Yes you do need a battery to avoid voltage spikes in the output of the converter/charger.
Your campground power source probably did not have anything to do with the converter starting to fail. However if the battery was charged when you left home, and everything was working correctly at home, then it might be possible that something failed at the campground. My guess from the limited information provided is that the missing battery caused the failure?
If your battery was not charged (you can leave the RV plugged in all the time to keep it full) then that can also overload the charger/converter and cause problems. Normally it just trips a circuit breaker, not spark. Sparking is indicating plugging into 220 volt power instead of 120 volt power, or a shorted wire from the batter to the frame. Or the battery + connected to the - terminal, and battery ground - connected to the + wire on the RV.
Let us know more information about the battery and it's connections.
