A well built surge protector for 30 amp trailers with extra diagnostics and a lifetime warranty. Pick an EMS instead if you camp where voltage sags.

Pros
- One of the cheapest ways to keep a campground surge out of a travel trailer
- Lights warn of a miswired or low voltage pedestal before you rely on it
- Weather shield lets it sit on the pedestal in the rain
Cons
- Only 825 joules, a small reserve against a big spike
- Does not cut power on high or low voltage, so a brownout still reaches the air conditioner
