Camping at a state park that just has 15amp service, its very hot, can you leave your RV plugged in and still run roof AC?
-- Be sure your fridge is on gas, not elect.
-- Make sure your converter is not charging your batteries. If you have batteries that are discharged to say 50% or you have a weak battery that the converter is trying to charge, the converter may be pulling 4-6 amps of 120V AC power.
Also, it is best if you have a way to monitor your 120V AC power. A multi meter is great, but something like this works great. https://www.amazon.com/Eversame-80-3...gateway&sr=8-2
It just plugs into any AC outlet.
Then give it a try. If the voltage doesn't drop below about 108V to 110V you should be good to go.
In the past I have run a single roof A/C on a diesel pusher motorhome on 15amp power.
Of course if the campground power is already low, say 110 volts and you try to run the A/C then it probably won't work. Or if the campground wiring is too small then you won't be able to run the A/C. The voltage monitor will show the low voltage so you will know that is the problem.
