Don't make this mistake. A dehumidifier can generate gallons of water per day...wait a month or two, and it will have overflowed potentially rotting out the floor.
As someone else mentioned, opening a roof vent is you best bet, just get a cover, so it can be left open in the rain.
If you insist on using a dehumidifier, just get a cap with a hose connection and put a small sag in the hose. This will create a P-trap, so no bugs going into the tank...not that I would really care if they did as there is no route to the interior from the gray tank.
very good advice. We live in an area with moderate humidity and use a dehumidifier when camping when conditions warrant it's use. It usually will pull 6-8 gallons of water out the first day, then around 4 gallons/day afterwards. Could fill a typical grey tank in a week!
Now some of that moisture is coming from us and what we do in the camper, but in the winter I use the dehumidifier in our garage and consistently pull 5 gallons of water/day out of the air.
