Question:

I realize that the #CAM55025 will not work if GFCI is in place. Most campgrounds use this. So what is the answer to my original question considering the inability to use #CAM55025?

For your 50 amp system, you will want the Camco RV Power Defender Voltage Monitor - 50 Amp # CAM55306. This voltage monitor disconnects when dangerous voltage levels are detected and then reconnects when it stabilizes. This is much better than the cheap surge protectors that need replacing and are only good for one surge and then leave you disconnected or vulnerable. You won't need a different surge protector for your 50 amp RV wiring.

For sites that won't have a 50 amp service, I recommend using the Power Grip RV Power Maximizer - 50 Amp Female to 15 Amp Male and 30 Amp Male # CAM55025 to give you 45 amps when available. This will plug into your shore power and then you will add your surge protector and then your power cord to your RV like # A10-5025ED.

The Power Grip RV Power Maximizer - 50 Amp Female to 15 Amp Male and 30 Amp Male # CAM55025 will not allow the 15 amp male to be used on a GFCI, so you would then be only able to use the 30 amp service if that were the case. Although many campgrounds do use the GFCI on the 15 amp outlets, there are some that do not and would allow you that extra amperage which is nice when it is available. Some sites will only offer the 30 amp service and your camper will still be able to utilize that with this adapter.
