 We have a 2016 177SE  which we just acquired and our testing in our driveway. I hooked up the power cord with a ponytail adapter to a regular 110 V extension cord  plug into a regular household 110 V outlet. Is there any reason why we can’t run the air conditioner this way?

The Dometic 13.5k rooftop unit on my Retro draws approx. 23 amps (momentarily) on compressor startup and approx. 12 while running. For ‘Driveway Camping’ I use a 30 amp (rated) cord and plug it into the 120V 20 amp freezer outlet in my garage. The breaker doesn’t trip and the cord and plugs stay cool to the touch even after running for several hours. 

The current draw for my unit was in the Dometic manual and I was able to find it online as well. Here is a link to a generic RV A/C power consumption chart:

you should be ok. We have smaller side mount ac a lots less amp draw. That 20 amp breaker should allow for inhush current(start up amperage) then settle down to running current. Some rv have a  circuit (breaker)on their panel for AC only.My Jayco has one but the Retro has AC and micro on same breaker so cannot run them together??GBA!!SVJ
