I have figured the inlet surge protectors are part of the Good Sam profit plan and unnecessary. What is the group consensus?

I have never used them and never had any problems. I guess if you have known erratic power and/or very sensitive electronic gadgets maybe so.

I use the Progressive Industries SSP50 Smart Surge Protector:

I suggest you read the reviews (granted not all "engineers") and do what comforts you.

Steve, for the sensitive stuff I keep a strip outlet on board, generally these are surge and ground protected and cheaper than the pigtail units.

Our late friend Lenny spent the big bucks and got a good one. In New Orleans the campground took a direct hit of lightning and every coach on both sides of Lenny was severely damaged, while Len had some burned up wiring and a few problems, but was able to move on. It cooked the pig but he immediately got another one. I haven't gotten smart enough to get off over $300 yet but I just might soon.

Steve the last time we were in Chattanooga, I has progressive 50 amp unit and it would not connect because of a bad ground. The park electrician came and checked the circuits and said there was nothing wrong, the eme would not let it connect. But it would connect on the other side.
