I have a 20 amp circuit from my garage, 100 ft 16 gauge grounded extension cord
(I know not nearly heavy enough) I will run my 15kw a/c but the voltage drops to 106.
I generally just use it for keeping the battery charged and running the small fridge in the front.

My test a while ago; From the breaker panel to the outlet the run is 52ft #12 wire and use a 20 amp breaker. Then from the outlet I use the #10 RV cord with adapter in a HD outlet.
When the AC runs at high I only have a voltage drop of less than 1 volt (normal is 120.8 Volt) When turning on the Microwave it dropped another 0.5 volt

According to Jayco's specs, an RV air conditioner draws about 17 amps, but I believe that is the highest spike up when the compressor starts up. I'm afraid the breaker will keep tripping.

Do not change a 15 amp breaker to a 20 amp, you could create a fire hazard. If a 15 amp is installed then the wires in the wall probable only support 15 amps. If you install a 20 amp breaker then install a new outlet wired with the correct gauge wire.

Whatever you use 20 amp or 15 amp breaker, run your refer and water heater on propane.
