Hi,
No question the PI is the better unit--but only if you need one. 50 amp it is good idea. 30 amp is unlikely to need such a device.
Piano... In many parks the 50 amp service is fairly new copper, more than heavy enough it is good solid power. This is because well, 50 amp rigs have not been around all that long.
However 30 amp sites may be aluminum feeders put in back in before I (I'm in my 60's) was born, And they have been eaten away to the point where the voltage drop when the air conditioner kicks in....
Well at this park I've seen 84 volts at the pedestal per someone's surge guard.
My RV is protected against this kind of thing, but most of the folks who monitor voltage shudder. The ones who don't... autoformers.
