30 amp ac
Can I run 2 air conditioners on 30 amp service without any other electric items on? Everything else would be on propane. It’s gonna be 92 here tomorrow (Virginia Beach) and I only have 30 amp service at my site but my 5th wheel has 50 amp.

you may be able to if you start them separately... If they should cycle on/off together then you may/probably blow a fuse at the power pole...
I would keep them on low cool. If the fuse blows with 2 on, then move back to one AC.
Try running a $20 box fan in the interior to move the air around from one AC unit... moving air feels cooler. You may even be able to run a separate extension cord to the 15 amp circuit on the power pole, not that your RV AC can use this, but the extra fan might need it.

It might be possible, but iffy. You can try a couple things. Run each one until warmed up and well lubricated and running easily. Will your generator carry both??? Run them on genset and then secure it to transfer it to shore power. It may transfer and hold fine.
An air conditioner on an average needs around 12-16 amps. The exact value depends on the BTU and the mode in which it is operating. A 15,000 BTU air conditioner in RV on an average draws around 12.5-13 amps. Where as a 13,500 BTU air conditioner will draw around 12 amps.

Probably not.

I wouldnt try it. I like the idea of a box fan to move the cold air.

It may work for a while if you start them at different times, but it will most likely not be dependable. You will also have some other shore power load from the converter.

To run 2 air conditioners on 30amp, I have to:
- turn off the charger/converter at the breaker (which then means I have to watch battery power and periodically turn off an A/C to turn the converter on to charge the battery)
- switch the fridge to 12v/propane
- switch the water heater to propane
- do not run any other high use appliance (no microwave, InstantPot, washer/dryer, etc.)
And depending on the strength of the breaker in the campsite pedestal- I've been about 75% successful.
BUT- my air conditioners have only been 15k and 13.5k. I'm unsure how two 15k A/Cs will work.

Well, been running both 15 BTU a/c on 30 amp service and everything is working fine. I have everything else on propane. Thanks to everyone for your input.

Do try to periodically give one or the other a rest. And check the prongs on your plug. Your power cord and plug will thank you.
