DW said stove was not heating properly. I looked at power control panel and L1 was showing 109-112 volts, L2 was at 119 volts. It is scorching and everyone in park was on full bore A/C usage. I shutdown electric heating elements and went to Oasis, not much help. Contacted park and they stated no one else had complained and my problems were from probably from my surge protector.
Has anyone else had this problem? Or am I being OCD, just do not want to ruin A/C's or other electronics. What is the lowest voltage one leg should see on a 50 amp system?

Thanks for any help with this!

Your EMS will probably shut you off when an input line drops to about 105-108. I've been having a similar problem. Line 2 here suffers a fair voltage drop on hot days. The AC is running, clothes on the dry cycle in the Splendide, me reheating my coffee in the nuke. A couple of those guys hit their start cycle concurrently and my Progressive cuts line 2 off because the V is down to 105. Not much you can do on these really hot days but control your own usage a bit.
As far as the park manager is concerned, pull out your trusty meter and invite him over to observe you take voltage readings on his power pole with your coach completely disconnected.

Not uncommon for CG power circuits to not keep up with high summer occupancy coupled with hot weather air conditioning usage. Especially if older CG and especially with many/or 30a service pedestals. If needed, I just fire up the generator and continue to keep cool.

You may have a faulty induction stovetop (if that is your problem). Mine would operate at half power if the voltage dropped below 115v. I got it replaced and the new one is fine. Yours may be from the same batch.

P.S. The Dometic service manual says the ac units should operate at 105v.

This might be one of those situations where a Hughes Autoformer or similar might be a good investment (spend more money) https://hughesautoformers.com

Nice video from RVGeeks.
