How do you know which one to get? Thanks for all of your comments and help.
From the horror stories others have shared, yes, I consider it a necessity. I just purchased a Progressive Industries portable surge protector for our new travel trailer. Lots of folks have one of these, or their built-in model. I went with the portable one, since it can transfer to any new trailer I purchase in the future.
The same could be done with a built-in unit, of course, but for me, it's just simpler to have a portable one. It has a lifetime guarantee and is made in the USA. After checking all prices and offers, I went with one on Amazon. The price there was several dollars less than models I found 'on sale'.
With a small length of chain, and a lock sized to fit around the units lead wire (that runs from plug-in to controller) I can easily secure it to any power pedestal. It's all-weather, very well made, and has an excellent reputation.
Good luck with your choice!
