The need will depend partly on what types of CGs you use. If you stay in older CGs, you def. want an EMS. We use mostly Thousand Trails CGs which are older and in the 5 seasons we've had a PI EMS in our current TT (30 amps), have seen reversed polarity, open neutral, open ground and most often, low voltage. I wouldn't dream of not using an EMS. Ours is hard-wired and is always there to protect us automatically when needed.
Low voltage in CGs is very common during the summer with everyone running AC units at the same time. It can be worse in older CGs too. An autoformer can be very helpful and keep you going when you'd otherwise have to be shut down. We use ours several times a season or more. Many people don't release the damage they are allowing to happen as a result of low voltage. Just because your AC is running under low voltage doesn't mean it's okay. Damage from low voltage is cumulative and lead to premature (and costly) failure of an AC unit. Checking voltage with a voltmeter when you arrive doesn't necessarily mean it will be okay the whole time you're there.
You want an EMS like Progressive Industries or a Surge Guard (which is much more than a surge protector) and not a basic surge protector only.
