Thoughts on the 'need' factor of a main line surge protector

In 14 years I've never had a known "surge" error with the RV. It might help but in my opinion you're likely waisting your dollars.

I'm glad you put the qualifier "known" in your statement. In 13 years (all but the first 6 months with the EMS-HW30C) I have had no "known" surges either. However, it has disconnected me from power several times for low voltage, and once for high voltage. Surges are not the only problem. I still call this cheap insurance.
