Some of the confusion is people are giving advise and making guesses thinking your RV uses 30a service. Ignore the 220, 240, and 30 amp responses.
Here is what probably happened; your RV experienced an open neutral either due to plugging into a hot outlet or a miswired receptacle.
Never plug into or unplug from a 50a service with the receptacle hot (on). If the plug is wiggled a little while inserting, a temporary open neutral can fry some appliances.
Your BIL could have done everything correct and the problem could still occur from plugging into a hot receptacle --- or he might have miswired the receptacle.
I test EVERY RECEPTACLE I USE with the RV BEFORE plugging in the cord.
This is the closest to what probably happened. IF your BIL wired a 4 prong 50 amp outlet and you burnt out the appliances, the odds are
1. he did NOT install a Neutral(white) wire and used 2 hots on the 2 hot blades. An open(not installed or not connected Neutral) will apply 220 volts to a 50 amp RV
2. OR, he install one of the hot leads where the neutral was supposed to be on the 50 amp receptacle
3. IF he wired a 30 amp plug and expected you to use the 50 to 30 adapter, he installed 2 hot leads on the 2 blades of the 30 amp receptacle instead of the Neutral (took a 220 receptacle and used a 30 amp RV receptacle, thinking it was the same except for the round ground pin when the 220 has 3 blades). That supplied 220 to your RV
4. I doubt the refer board is bad, the 120 heat element fuse is blown on the board and "maybe" the 120 element blown also(happens, but rarely). Doug
