I wouldn't be o sure you can't do that. You can run the A/C (one unit) on the single 20A circuit. A heat pump doesn't have any electric coils for heating, so it doesn't draw any more amps than the AC side. Just don't plan on using the microwave at the same time. Also, be sure you have a good heavy cord for it. I ran our old RV's AC in our drive on the 110V outlet for three years without any issues.

Another dumb question - heat pump VS gas heater

A heat pump draws the same amps in heat or cool. I ran mine on a 20 amp circuit with a #10 extension cord. There are no heat strips in a heat pump. An a/c with heat strips is only 1400 watts on heat.

Before I installed our 30 amp rv receptacle I plugged our rig into the 20 amp gfci receptacle on our porch using an adapter cord. Curious how many amps the ac/heat pump actually used, I inserted a Kill-a-watt unit between the rv & porch plug. Before turning anything on, the rv was pulling 4.5 amps, probably the fridge and converter. After turning on the AC I was drawing 16.7 amps and heat pump, which I expected to be the same, was a few tenths of an amp higher.

You can run the heat pump on a 20 amp circuit just fine as long as you don't try to run anything else in the RV except a few lights. And, make sure nothing else in the house, garage etc is on that 20 amp,circuit.

Just get a good quality dog bone type adapter that will make the transition from your 30 amp power cord to the 20 amp outlet. And, of course, make sure it's really a 20 amp outlet, not a 15.
