30 amp 240 volt mistake!!
I recently bought a 2018 Rockwood 5th wheel with a 50 amp service. I have a 240 v 50 amp outlet in my RV cover that I’ve used for years to plug my motorhome into. Since I still have my motorhome and i...

Sorry for your troubles.
I think someone mentioned it already, But I will suggest a EMS unit (Progressive Industries makes a good one). I had a hard wired one in my last camper, and it was the first thing I put in my new one. It will cut power to save the rig in the event something like this happens in the future. I have not run into issues with miss wiring yet, but have had too low of voltage at older camp grounds.
Yes, my converter was smoked too. It was a cheap one anyway, so I just ordered a new Progressive Dynamics PD9260CV Inteli-Power 9200 Series Converter/Charger with Charge Wizard - 60 Amp to replace it.
Good choice on the converter; the PD ones are spec'd to shut off and not do anything bad for overvoltage conditions up to 240ish volts nominal.
Do be aware that an EMS and the converter are quite separate and different things (and Progressive Dynamics and Progressive Industries are likewise two entirely different companies, albeit with confusingly similar names). An EMS, at least as discussed here, is a gizmo that is installed somewhere around the electrical inlet of the RV and monitors the voltage, frequency, etc. of the incoming power and disconnects it--or refuses to connect it initially--if it's not correct. There are also some more sophisticated Electrical Management Systems that higher-end RVs may have that perform additional tasks like load shedding based on the available power (for instance, disabling the electric element in the water heater for a 30A shore power connection, or preventing simultaneous use of multiple air conditioners under similar conditions).
