Surge protector works great. We carry an extension cord for when the unit will not fit into electric box provided by campground. We then put it into the compartment of the motorhome where the unit is out of the elements.

I have used this everywhere I go, never had a problem plugging it in. 2nd time I used it there was a problem and I asked for a different site.

I purchased this RV Surge protector to use with a travel trailer at seasonal campsite in 2008. The unit worked great and fit the pedestal electrical outlet. The cover of the pedestal did not close Completely due to the body of the unit plus the type of cable I used to connect with the trailer. It was closed enough to keep out any excess moisture. My camp has a newer electrical setup and we have not experienced any issues but I do feel better having the protector in place and will be using it again when camp reopens in April. I would recommend some form of surge protection for any RV or trailer whether traveling or seasonal. Should I upgrade in the future to a newer trailer, I may consider a full unit surge protector that would be built-in or permanent to the trailer.
