I headed down to the basement and brought up my Maytag dehumidifier. This is a 45 pint unit. I usually empty it once a day in the basement during spring and humid weather, but I'll bet it will need emptying at least a few times per day with this camper right now.
This unit has an option to drain the water away via a hose, so I'm going to see about doing that tomorrow morning when I take it out there. Then I don't have to worry about it shutting down as "full" while I'm at work.
I love this thing, I've had it many years and it works great. Model M7DH45B2A
