Good point - I'm pretty sure that most, if not all, of the general purpose outlets in our trailer are on one circuit (exceptions I know of include the microwave, the converter, and the fridge). If that's the case, it may not be possible to run two electric heaters at a full 1500
watts each in the camper.
Personal opinion follows: Having used electric heaters in campers myself, I firmly believe that the best solution for heating the camper to be comfortable is the built-in furnace. It uses propane rather than free electricity, but it works so well compared to space heaters that the cost is worth every penny. And it doesn't take up space on the floor. (I am kind of trying to talk my wife into a small, unobtrusive wall-mount electric heater for the bedroom to help out the furnace, though. The furnace just doesn't get enough warm air back there.)
