I know this is shocking news to you, but If you stick your finger in an electrical outlet, the current can maim or even kill you.


One of the projects I completed during my stay at Gulf Islands National Seashore was to finally install the internal surge guard to protect my electronics. I purchased this system over two years ago, and, like so many projects, I put off the installation until "some day". I thought about it a lot, and following the rules of procrastination, I thought about it about 10 times longer than it would have taken to just actually do the job.


I had this same system in my previous motorhome and loved it. In that situation, the power supply, the fuse box, and everything else connected was easily accessible below one of the dinette seats. I had the entire job done in one afternoon, and wrote about it here. But, with this motorhome, all of that electrical, including the fuse box, is below the refrigerator, and most certainly the installation at the factory was done before the refrigerator was put in. That would have been pretty simple. Now, I had to do all of this lying on the floor, with a flashlight, sometimes holding a small one in my mouth, and it took all day.

On top of that, getting the remote monitoring panel installed where it would be most useful, right over the microwave was a real battle, and it took me two days and a trip to the hardware store to buy an electrical snake to get the cable up and over the refrigerator, and behind the microwave. But, it turns out I couldn't get that snake through the maze of factory-installed 120 volt wires behind the refrigerator, they were packed in there solid. I imagine the fellows the plant thought, "well, nobody will ever see these again ... "

I wound up on the roof, removing the cover to the refrigerator "chimney" (RVers know what this is, a passage way to get the heat from the back of the fridge up and out to aid in the cooling process), finding those wires and adding my monitor cable to the mess.

No matter what kind of RVer you are (part-time, full-time) you should buy a good surge protector. It’s well-worth the investment. Click here to learn more.

One of the advantages of an internal device is the ability to protect your electronics not only from the RV park power pedestal, but also from your own generator, those things are spikey. I know I was saved from damage in my old motorhome when the generator went nuts, putting out 135 volts or more, and my surge guard shut everything down.

Cost is a factor, an external guard can be had for a hundred dollars or less, the internal system is three or four times that, but for me it is well worth it.

External surge guard devices only protect you against bad RV park electricity, not the built-in generator, something motorhomes have, but travel trailers and 5th wheelers usually do not, relying instead on external portable ones, often carried in the bed of the pickup truck*, where that external device will do a good job.

*The last time I remember seeing an automobile pulling a large trailer was in the 1954 movie "The Long Long Trailer" with Lucille Ball and Desi Arnez, as they struggled to get a 32' 3 ton New Moon trailer up and over the mountains with a 1953 Mercury six-cylinder convertible. I have a copy of that movie, and watch it about once a year. One of the advantages of being old, it's brand-new to me every time. I wish they'd taken a shot of the temperature gauge as they were going up that mountain.

I'm starting to run out of projects on my to-do list. Oh, wait ... I just thought of one.
