A buddy bought a portable surge protector and I was going to get the same, but after some research I discovered I could install the hardwired unit myself, so I purchased the
Progressive Industries EMS-LCH W30 unit. I decided on the hardwired model over the portable for 3 reasons: I can't loose it, it can't be stolen from the campground electrical pedestal, and the Fault code reader is mounted inside the trailer.
Here is my
install video. If you follow the enclosed manufactures directions its an easy install.
Full Disclosure: I am
not an electrician and if you don't feel comfortable doing electrical work then you should have it professionally installed.
