There are campers that have been camping all their lives and never had a problem with electrical surges, brownouts, lightening spikes, mis-wired pedestals etc and there are campers that have had several issues....usually in unfamiliar campgrounds. When we owned our old Jayco TT, I didn't have a lot invested in electronics or gadgetry. With 'The Beast', this fiver is more of a second home and I have far more invested in high end items that would cost mucho bucks to replace. I weighed the cost of a surge protector against the cost of replacing each built-in and portable electronic gizmo if we got zapped and the surge protector won out. Sure, I had to pass on a few nice convenience items in the trailer until later in the season, but the peace of mind knowing that I'm protecting my trailer is worth every penny spent. We camp at unfamiliar campgrounds a lot more often with this trailer as we're looking to see where our retirement state is going to be. Not knowing good hookups from bad, I wasn't willing to roll the dice at perhaps 10-15 new campgrounds every season. Sooner or later the law of averages catches up with you. The only downside of the PI surge protector I bought is the low voltage cutoff if you have a hot night and everyone is running their AC units. Hmmm...still trying to 'splain my way through that mess with Wifey when it happens, and it's bound to happen sooner or later. That speaks volumes for Frank's Auto transformers like Herk has. It seems like the best of both worlds but you have to be willing to spend the extra bucks. They ain't cheap. You also need an area large enough to house that unit. They are not necessarily compact in size. Good luck with whatever you do.
