Hello my name is Lyly and I'm new on forum!

We have a Keystone Vantage 2012. My question is: can we run air conditioning on electricity 30 amp (120v) and the rv fridge on propane both at same time? We don't travel with the trailer, we're parked permanently on camping site. We want to save electricity and use more propane for the fridg as we have no choice using electricity for the air conditioning! Thank you!

One AC and the fridge is no problem on 30A. But there are things in the background that run out of sight, like charger inverter etc.. you have to be mindful of.
Sometime people forget, and try to run microwave, stove or hair drier (my wife did it) on top of the basics, and trip the circuit breaker...

Thank you for replying! I know about not overcharging the RV , that's why I want to run the RV fridg on propane and air conditioning on RV electricity. There is an electric pluging 120 v 30 amp on camping site. Do you know if it's possible running both electricity and propane at same time?

If the converter does its job correctly, you do not have to be concerned about overcharging.

The AC is strictly 120 Volts and will run easily on a 30A service. The refrig does require a small amount of 12V DC from the battery or converter to power the control panel. The LP has basically nothing to do with 120 V or 12V consumption. Plug into the 30A service, turn on the LP, and enjoy your day.

Your refrig can run on 120 VAC drawing about 2.5 amps or about 275 watts. Still, that is no issue for a 30A service and the AC at the same time. The AC will pull about 15 amps or 1800 watts. Of course, you can manually switch your refrig to LP, but still, 12 V is needed for the control panel.

Everything should be automatic if working correctly.

I'm not completely sure if I understand but I'll try to figured out with the trailer's instructions.

Twelve volts from the vehicle battery is required to run the printed circuit control boards on many of our appliances. Without a good way to keep your battery voltage up (your AC-to-DC converter should be sufficient), it might struggle running on propane. Same for the interior heater for the vehicle and perhaps the water heater.

A small Harbor Freight set of solar panels and charge controller solves this problem easily and rather inexpensively - about $150.00.

Thank you for replying!
Well I try avoiding another expense and an extra $150 is not necessarily a solution for me.
