If you used a standard 50/30 dogbone adapter be aware that the adapter connects both hot legs of the coach together. Meaning you put 240 on both hot legs, not just one.
You can not put 240 volts down both legs. A 30/50 adaptor takes the one 30 amp 120 volt leg and puts that 120 volt leg on the 2 120 volts legs of the 50 amp cord. 120 volts @ 30 amps down both legs.
A 50/30 adaptor takes just 1 50 amp leg and put in down the 1 hotleg of a 30 amp cord.
you can not get 240 volts on one leg of a service in the US and Canada. That only happens in european countries.
This is only true if you plug into a 120V circuit. OP plugged into a 240V outlet, which would have put one 120V circuit on both hots going into the RV and then the other 120V circuit on the RV neutral. This makes both sides of the 50A circuit in the RV 240V.
