50 amp RVs are wired exactly like a house. Nothing special. There is 240 available but most electrical devices use only 120 vac.

This can be half right, that there is 240 volts in the RV that isn't used, but there can also be 208 volts, depending on the transformer serving the RV park. So, it really doesn't matter what the hot to hot leg voltage is, so long as the hot legs to ground or neutral is 120 volts. If you do use a meter to check voltage, do not panic if you see something in the range of 208 volts hot to hot. This is the sticker on our rig next to the shore cable receptacle.
