Does 50 amp hookup actually have 240 vac in the RV?

[BB_TX]

Mixed in the discussion of campgrounds prohibiting using a 50/30 adapter to connect a 50 amp RV to a park 30 amp outlet, there was a side discussion on whether there was actually 240 vac available in a 50 amp RV. I guess like everything else there is no consistency.

Someone mentioned that their distribution panel did not allow installing a double pole breaker for 240 vac. Mine however does. It is an IOTA IDP-240 120/240 VAC ELECTRICAL DISTRIBUTION PANEL. I suppose the 120/240 means it is configured for either voltage using the appropriate breaker. The breaker spaces alternate between hot 1 and hot 2 just like a home electrical distribution panel. So if I wanted to install a 240 vac clothes dryer (or any other 240 vac device) all I would have to do would be install a 2 pole linked circuit breaker and run the appropriate wire to my dryer closet. Not that I have any reason to do that, but it is possible.
