replace transfer switch with 50amp plug?
I have a friend who's on some hard times and living in an older HR pusher in a park. It sounds like his transfer switch has croaked. For a while he would lose power from the pole and it would on...

Transfer switches have what is called "break before make" relays to prevent from ever having two sources connected at any given time.
An arc can occur when the relay disconnects from its source with appliances turned on. Over time this corrodes/pits the contacts and enough resistance occurs preventing enough current to pass or weld the contacts together so they cannot disconnect.
The relay contacts can be cleaned with 400 grit sandpaper but this is a temporary solution and eventually you will have to replace the contacts or the transfer switch.
