LP gas Regulator... better brands?

So one thing I can’t understand. I have a rental townhouse that I’ve had since the 80’s.
It has natural gas service. I guess there is a gas regulator on it, but I wouldn’t know...CAUSE ITS NEVER EVER BEEN A PROBLEM IN THIRTY YEARS !

Then how come i am now preparing to change out my two tank regulator for the second time in four years?

I did the percussive tuning thing before. I tried whacking it again and no dice this time.

It’s a Camco model.
Is there a better brand choice?

Thanks
