I opened up my electrical panel today and saw that I am only using 3 of the 4 wires inside. This is in a trailer with a 4-prong, 50A RV hookup. I have called two electricians and both said different things, so before I hire someone to do this I would like some advice.

Since this is the case, could I just remove the 4-prong end and use some kind of heavy-duty, 3-prong 120V male end on this? I have a 50A box, however, I'm running less than 30A on it, maybe even 20A if I actually added it all up.
