Glad I have my power monitor
When I got my new trailer, I bit the bullet and bought a EMS-HWC30 power monitor. My old RV developed odd power issues and I'm pretty sure it was due to all the bad power I plugged into before I knew any better.
Still, it's a tough decision to fork out around $300 for something that *might* not really be needed. We are so used to having clean power come out of the wall in our houses that it seems like it should be the same thing in a campground.
Well, I'm sure this thing has earned its price. Just this weekend we set up at a site and plugged in. We always try to *not* run the A/C if we can help it but it was hot so we turned it on. About a minute later the power cut out. I took a look at the display and we were only getting about 104-105 volts. If I hadn't had the power monitor, I would have happily let the A/C work at that level, doing who knows what kind of damage that might only be apparent down the road.
They eventually got the volts up to about 117-118 the next day, which the power monitor was okay with. If anyone is on the fence about these things, do it. Campground power is pretty risky and there are enough other things that are going to go wrong with your camper. Don't throw bad power at it too.
