Surge Protector

We recently moved our fifth wheel into our new seasonal spot, my question is we are connected to a 30 amp service, my designer is setup for a 50 amp service as well. I want to install a surge protector for my camper but i'm not sure which one to choose, I know there are alot of choices to choose from on camping world website but i'm lost when it comes to which one to choose. Also has anyone had an experience that the protector saved them at the campground? Thanks for any recommendations.....

Yes, I have heard a few reports of people being quite glad they had a surge protector.
Interesting that your CG provides 30A shore power, but your Designer has a 50A requirement. I would suggest using a 50A surge protector, because in the future you may find yourself with a 50A shore power source. The 50A supply actually has two live leads, one neutral lead and one ground lead. The 30A surge protector is only set up for one live lead, which is the norm for 30A shore power.

Use the 50 amp... it will still protect you when you are on 30 amp service BUT a 30 amp wont protect U when you are on a 50 amp service.

I agree, go with a 50amp surge protector. Also, with 30amp shore power coming into your FW it will only run one A/C unit, it won't support two A/C's if you have them.

I installed a 30amp hardwire PI-EMS in my TT (30amp) last week: https://www.jaycoowners.com/showthread.php?t=6896&page=3
