surge protectors
Hello all. Recently bought a DP and am curious to know about surge protectors. I have RV'D for the past 40 years with everything from a cab over, a class C to several 5th wheels. In all those years, I...

Progressive Industries Portable Electrical Management Systems (EMS) provide full RV protection against all adverse power conditions. You will feel secure with multi-mode surge, voltage, polarity and lost/open neutral protection.
Without numbers for each feature, then nobody can answer honestly. Even a knot tied in a power cord is protection from some of those anomalies - as long as we forget to include numbers.
Progressive protects from some anomalies (called surges) such as insufficient voltage. Specification numbers are essential to say how much; either near zero or effective.
A 'whole house' protector does not claim to protect from common anomalies found in campgrounds - ie insufficient voltage.
'Whole house' protection does protect from direct lightning strikes if properly installed. That means it must connect low impedance (ie less than 10 feet) to what harmlessly absorbs hundreds of thousands of joules. That same low impedance requirement is why a Progressive must connect at the pole (as close as practicable to an earth ground electrode) to provide similar protection.
A 'whole house' protector (or Progressive) too close to appliances and too far from earth ground (ie inside a camper) means protection from that type of surge has been compromised.
Effective answers require numbers. Any claim without numbers can all but prove it can save the world. Each and different anomaly (all called surges) must be discussed individually and quantitatively to have a useful answer. That quote is best ignored since each claim is only subjective (qualitative).
