Hi,
Tolerance is often (but not always) 10% so 115 name plate suggests that 103.5 is the lower limit. With 120 volt that becomes 108 volts.
I'll stick with 108 myself for the lower limit.
I do know that last year at a campground on a hot sunny day I had to turn off everything except for the air conditioner. This summer if it is hot, I'll spend the money for a 50 amp site (if available).
The air conditioner was drawing over 1900 watts. That is a sure indication that voltage was too low for my comfort zone.
The thirty amp pedestal breaker blew twice with just the air conditioner running. I suspect old tired breakers and minimal wire size in the RV park.
There is an autoformer in my future.

OK But what is the lowest voltage for the motor? My Dometic says 115V period. So do I turn it off at 114V or at 107V or whatever?
And your motor may be different and it may not be 108-132?
Just raising what-ifs?
