You arrive at the campground – about to connect your truck camper to the power pedestal – is there a moment of hesitation, or are you confident the
pedestal is wired correctly?
Is there an open neutral? Are the lines properly phased?
What protection do you have against a bolt of lightning that strikes a telephone pole a 1/2 mile from the campground during a thunderstorm?
Should you encounter a surge in power, have you considered the cost of replacing your electronic equipment? Such as the computer(s) that is filled with your records and photos, Kindles/iPods, the microwave, refrigerator, HD television. The camper’s equipment such as slide-out(s) and/or jack motors control boards? 
With today’s RV containing sophisticated and sensitive electronics, faulty electric power or a power surge can damage these appliances or electronics.
Question – should you encounter an electrical surge that damages your truck camper’s electronics, do you feel strong enough and know how to hand crank in your slide-out(s) and raise your jacks?

Surge protectors are a necessary safety device. Just as important to your and your family safety as the CO2/LP gas and smoke detectors.
