Campground voltage vs fridge performance

The campground we are staying in for the fall has voltage problems. While we may see 120-122 in the am, by afternoon it drops to 110-112. At least once it dropped low enough that the PI shut down the system. Question? Our Norcold 1200 isn't getting as cold as it used to. Still ok, but the ice maker doesn't keep up like it used to. Coluld low voltage be at least part of the problem? BTW, afternoon temps are in the mid 90's.

YES Low AC Voltage CAN affect cooling process IF using electric heat element.

Fridge will continue to operate on 108V AC thru 132V AC
Electric element is 225W (2 elements used and both have to be operating)

The lower the voltage the lower the heat generated
Lower heat------less ammonia liquid turned to vapor ----less cooling

Swap over to propane when AC Voltage drops

Course there could be other issues......
Insulation that is blocking air flow (draft)
Fan(s) not running
Cooling unit obstruction/blockage in tubing

Thanks. That was sort of what I was thinking. Of course, when I got up this morning we had no power at all! The whole campground is dead. And it is packed for the weekend. Maybe they will be forced to address some issues. I've got a full tank of fuel, but the generator is a bit noisy when I'm sitting outside.
