What are the best RV surge protectors?

I broke down the list between 50 amp and 30 amp. The prices do range from less than a $100 to over $600.

These surge protectors will keep your RV electrical system safe from most electrical inconsistencies.

I'm sure you're wondering by now "Do I need a RV surge protector?" or "Why use a RV surge protector". Many of us look at the costs associated with a surge protector and choose to put something like this off for a while.

I know we did that until we were at a state park with inconsistent voltage. We didn't have a surge protector and I could smell my electrical wires start to burn. After changing out many of the burnt wires, I realized that having RV surge protector was well worth the money.
