In a short answer - yes you can do too much dehumidifying - when occupied. Too dry will dry YOU out.
Unoccupied, it is not necessary to dehumidify a camper.
If you are wondering where all the moisture is coming from when unoccupied, it is likely from the surroundings. Like your air conditioner, even if you don't open any doors the unit has to cycle on to remove the heat through absorption. Campers, like homes aren't drum tight. Moisture is migrating from outside.
After a trip in the coach it would be ok to run the humidifier for a couple days to dry it from the occupants but you will not likely ever to see a day of never emptying the bucket until the outdoor average daily humidity levels are around 35% or lower.
