Set me straight...AC on 120/20amp outlet.
So I've been reading a number of threads talking about running the RV AC on 15/20 amp outlets. So I looked at my breakers and they are all 20 for the house, I currently run a 50ft 10ga extension cord...

I would read the manufacturer's electrical info. The issue is not only voltage while running, it is voltage on initial startup. This Coleman info. (see page 7) states a min. of #12 ga. and that for lengths greater than 50' you should use #10 gauge. This would include the shore power cord plus length of run from the recept. to the house panel.
Starting inrush current (locked rotor amps) is around 5-6 times running current and for the above Coleman 15K unit, is 63 amps which can cause a high momentary voltage drop. Running current is listed at 15.3 amps and breaker just for the AC is 20 amps, and you may need to keep all other loads to a min.
Ensuring the voltage is good is the key and I would use a permanently mounted LED voltmeter inside to keep an eye on it.
