Is it? What follows demonstrates why some "most expensive" protectors can even make surge damage easier. In rare cases, even create a fire.
Which surge is a concern? This subjective term can be about too little current, overvoltage, too much current, a sharp spike, noise, polarity reversal, floating ground, too little voltage, harmonics, frequency variation, ... Which anomaly does your surge protector protection from?
Protectors that are profitable scams are one shot devices. No effective protector fails on its first anomaly. By grossly undersizing it, then a majority (who forget concepts even taught in junior high science) will recommend that grossly undersized and obscenely profitable 'magic box'.
Asus computer boards can report a surge. That is a low voltage. Computer USB port can report a surge. That is too much current. Neither do what a 'whole house' protector is for in homes. Surge protectors for RVs are for completely different anomalies such as reversed polarity or low voltage. To protect motorized appliances from something that does not harm electronics.
One can never recommend any protector without first defining what it does - with numbers. Any recommendation without spec numbers is best considered bogus. Some RV protectors will only protect from an overvoltage. Others might also protect from surges due to direct lightning strikes. The word 'surge' can mean most anything. Naive consumers assume that near zero protector circuit in a power strip will also do what an RV protector must do. Because most use word association rather than concepts even taught in school science and math.
