50 amp service - is RV service wiring the same as others?

Our trailer is wired for 30 amp service. I carry a 50A to 30A dog bone adapter for situattions where only 50A service is available. Next week we will be "camped" next to a utility shed on my cousin'...

Most welder outlets are 3-wire L-1, L-2 safety ground (no neutral) and not suitable for RV use.

HOWEVER it it is 4 wire and the 50 amp end fits... Go for it.

BUT.. before you plug in the rv, take a volt meter and mneasure the voltage between the two FLAT blades on the 30 amp outlet.. Should be 110-125 volts, if it's not, No joy.
