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 only run on generator.

Then it stopped getting power from either source.

He really does not have $150-200 for a new switch.

My suggestion is that he wire it the way my much older coach is wired,

The AC cord goes to the breaker panel. The generator goes to a female 30 amp plug. Instead of a transfer switch i plug the RV cord into the plug to operate from the generator.

I am a fair electrician but i have not been out ot see just what htis would entail

Any thoughts or opinions would be appreciated.


thanks
