My understanding is you want to be between 114v and 126v, does this fluctuation for only short periods of time (like using a hair dryer) cause a problem? Obviously hair dryers are a big voltage draw and I'm sure space heaters would be also.

If your trailer has a 50A service, you do realize that the plug in volt meter is only going to tell you voltage readings on 1/2 of your incoming power. The other side of the service is not being monitored with just one plug in voltage monitor. If you have a 30A service coming into your trailer, please disregard what I just said.
