It depends on the ambient humidity and outside temperature. It is entirely possible to have a situation where the air in the rv is uncomfortably wet. The solution is to add some heat which basically turns the roof air into a huge dehumidifier.
If you have an oversized air/con, there is some truth to your idea as it will force the air/con to run longer to remove the heat you are adding which by default will provide more moisture removal.
But the OP said the air/con runs "pretty constant" which to me suggests it shouldn't need the heater trick to get the dehumidifying effect as it's already running enough to pull the humidity out of the air.
Which leads to the question...what is really happening?
given the size of the trailer the OP mentioned, I wonder if the AC fan is running but the AC compressor is cycling, which can be the case depending on how the thermostat and AC are set up.
If that is the case, a compressor driven dehumidifier may be the solution.
