There are various surge protectors and power protectors available for RV's. The most popular one seems to be the portable type that plugs into the pedestal. Hence no installation but subject to not being installed. The hardwired version has to be installed in the rig but is always available.
A pure surge protector protects against transient voltage as in very short duration voltage spikes. I believe that this type of device has limited value for a RV.
The full power protection devices are often called surge protectors but they are much more. They include pure surge protection, miswired or faulty plug wiring, high/low voltage protection and frequency protection.
The best full power protector is the Progressive Industries units. The HW50C model includes a remote which displays voltage/amps for each hot leg, frequency and displays an error code for any faults. It has better specs than the Surge Guard unit and has field replaceable parts.
Mine has detected 3 cases of reversed polarity on a 30A plug and numerous cases of low voltage.
Plus one night on a 30A plug it shut down the rig with 160V. The problem was a bad neutral in the 240/120V CG distribution system and I ran to the pedestal to pull the plug.
Many on these boards post 20 years with no power problems and no need for protection. I also went 20 years with no protection but with many new rigs and always on AC appliances it should be considered before the smoke gets let out.
My HW50C is in a second rig and was moved without cutting any of the original wires so quite easy to move again.
