arrrggg..
All voltages in the USA as long as I remember is called 120V / 240V..
Not 110, 115, 220, 230...etc...as stated below.
The OP has a 50 amp plug as he has two A/C's
First lets ask what adapter are you using as they are not all created equal.. Some will only power 1/2 the RV as both legs in the adapter are not tied together...
In either scenerio you will only be limited to 15 amps regardless..
Are you going 15 -30 - 50 or just 15 - 50?
Whats the make and model of the adapter?
You will not have issues but need to watch what you use..
