Recommendation for heater?

Im afraid I dont know the numbers. But my setup is a normal outdoor (Im assuming 120 volt) outlet from a house with the thickest gauge extension cord they had at local harware store and an adapter to my camper. I can run many things at the same time, computer, tv, instant pot, fan, even a/c and I never had a problem but the space heater on high was a bust. And I didn't even try to run it on low, I just didn't want something that could provoke an extra headache for the property owner with the circuit tripping. Truth is I am fine paying the propane price for heating but if I could supplement that with an efficient space heater I would be happier. I assumed there would be someone on here with such experience. I'm not looking to find the exact wattage or amps I can run within a certain breaker, a small, simple space heater that doesnt max out the wattage or amperage that would trip a breaker is what I'm looking for. Hopefully something efficiently designed and worth buying in my situation.

Unfortunately, you do need to know the electrical draw and availability of amps. Otherwise, you and everybody here are just guessing.
First thing is the size of the circuit breaker that is flipping and what else is on that circuit in the house. When you draw more amps than the breaker is rated for, it shuts the circuit off. When it flips, are there any things in the house that stop working?

Try running the heater on low and see what happens. As stated before, basically all portable heaters use the same amount of electricity on high. Some may be more efficient in their use, but 1500 watts is 1500 watts no matter what is using it.
