I am interested in buying a 30AMP surge protector for our new camper.
I have done some research and haven't really decided on exactly what model I want to get.

Do any of you have any input on what has been good or bad to you?

I actually have a 50AMP TRC that my parents bought a few years ago that was re-manufactured when it had some issues. TRC sent them a brand new one then refurbished this one and sent it back to them. It's never been used since then. I'd love to be able to swap it out for a 30AMP or somehow use it but I don't think it's possible?
