The tingling is definitely not normal and may indicate a dangerous situation. Did you check the 30 amp service at the campground service box? Or did you check the service inside your trailer? Or both?
The readings look normal to me. But if you checked it at the service box -- certainly the first place to check -- did you also check the AC within your trailer? There could be a problem in the umbilical, the plug, or the umbilical installs in your trailer. So I'd suggest taking those readings from an outlet in your trailer.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
