Hi from Tampa/St. Pete. We've been full timing since 05 (no house/no stuff) and have used a 50 amp SurgGuard from the git-go. Now, I'm no electronics whiz by any means, but we do KNOW that our surge protector HAS tripped out and apparently saved our circuitry from overloads at least three, perhaps a couple more times, since we've been using it. We use a portable unit which we store with the cable when traveling and simply plug it into the campground pedestal when parked and hooking up. Never had ANY problem with anyone trying to steal it. We think it's a good item.
