Have you ever tried running two AC’s on 30 amp, only to have the breaker kick-off after a short period of time?
With a little care, yes, it can be done and you can cool even a large RV on a hot day. I would suggest you install soft start kits on your AC units, I actually still need to get this done, but you can still do this without them, you’ll need to reduce the amount of electricity you are using, and to help with cooling, we installed RV Airflow System units in all 3 of our AC units.
