Can you run x2 1500watt space heaters from a standard 110v shore line in the driveway or does it pull too much power?

As far as the brand of mine. It is an Spt but all single and double hose portable heat pump/AC units work the same way, except a double hose unit uses outside air.
My heat pump, with the single hose draws ambient air from the RV cabin. Some of that air is passed over the condensing coil, heated, and blown back out in to the RV.

HEAT mode
1. When HEAT mode is selected, the ambient warm air will be recycled and utilized to heat the
area where it is required. The Exhaust Pipe must be fitted properly to exhaust the cold
air outdoors.
2. Continuous drain is mandatory when unit operates in heat mode.
3. The working temperature range for heating function is 45~77°F/7~25°C. If ambient
temperature is outside this range, the unit may not work properly.
Might be it.

As winter comes on it looks like I am not going to get way south. Going to spend the winter in the Dallas area as my son gets well in the hospital. So with that said I wanted to ask if and what type of electric heating I should consider for my 36ft Damon. Thanks for any info.

It's nice that it works
Nobody is saying it doesn't work
Only that you are confused on how it works
It's called a 'pump' because it moves heat from the outside air to the inside
It does Not extract heat from air inside to move it inside
You have a hose to the outside and that is where the heat comes from the 'outside' air

A heat pump works by taking heat from the air in one place and moving it to another. Thus the term “pump”.
You cannot with a heat transfer pump take heat from a single space and put it back in the same space and end up warmer than before. Extra heat requires extra BTU’s, period.
If your unit is making heat without an external source of BTU’s it is from the parasitic (friction) losses of the pump and motor running.
The only concepts I can grasp are facts and science.
Magic and hokus-pokus are beyond me.

I’m not going to make this a long dissertation, but unless your heat pump is capable of extracting more BTU’s per CFM than than the incoming air contains, you’re losing heat, not gaining it.
A heat pump works by extracting the few BTU’s cool (cold?) air contains per cubic foot and it’s not a high percentage at all.
If it was a high percentage like you describe, nearly every house in America would have heat pumps.
