Another surge guard question??

Don't know how your RV is configured, but wherever the electric cord comes into your camper, it should be behind a panel, somewhere. You should be able to remove this panel and look inside to see how the umbilical cord comes into the camper and is attached to your converter - power supply. Somewhere between the space where the cord comes through the wall from the outside to the power supply converter, you should find a surge protector. If none is there, I suggest you call your dealer and have them look it up and tell you where it is, if one exists. If none exists, you can install a permanent one inside your coach, get one that attaches outside the coach on the electric pole-plug. Somewhere inside the coach, you should have a panel you can remove so you can see where the cord is.
