Progressive Surge Guard Recommendation

Hard wired or portable doesn't make any difference from a safety standpoint, but I can tell you after 4 year of full time use I would NEVER plug my 5'er into ANY outlet without my PD EMS. I have seen too many issues in campgrounds, been shut down myself so many times I don't remember the total, and even once at my home base site for high voltage. A transformer was failing in a residential neighborhood where there are 8 homes and my rig on one transformer. You just never know.

I even have a spare PD EMS in a box to use if my primary one ever fails or dies while saving my rig and has to be returned to PD.
