I have a 15000 BTU DuoTherm and a 13500 BTU Coleman. I am going to a campground that only has 30 amp plugs. It's going to be warm. If during the heat of the day I shut everything else off, can I run both ACs?

you might get away with
IF
you start both in the morning one at a time placed on full cold so they never cycle
BUT you are very likely to overheat and damage the end of your power cord adapter and possibly the cord itself

if it gets hot and melts or burns, you may end up with NO power what so ever
or overheat and damage your A/C,s from low voltage and high current

And if everyone else is doing the same, you may not even be able to run one.

I would recommend just running one unit at a time. Front during the day and rear at night. Otherwise your really pushing the limits. We did run both of ours full time last summer and had no problems, but we watched our amp draw like a hawk lol.

My Bounder has an EMS that allows you to turn both at the same time but fridge, water heater have to be on propane and no other major appliances on.

I am not experienced on the 50AMP shore power plug but there may be away to use adapters and run one air conditioner off the 30AMP service connector and the second air conditioner on the 20AMP service connector. I would imagine all of the 50A pedestals have all three services available...

Maybe someone else can dime in here. I think I read something to this a few posts back...

It may have been someone had run a separate 20AMP circuit connector to the bedroom air condition and just plugged this one into the 20AMP service on the pedestal. All three of those service points on the pedestal should have their own separate circuit breaker...

Might be something to plan for...

Best way for me to answer: "It is like trying to suck a whole watermelon thru a soda straw"

It is not going to happen....
