I lived full time in my trailer by myself. I bought a 25 pint unit from Lowe's. I had to empty it 2 times a day, which was about 10 pints each time. When I took daily showers I opened and ran the bathroom exhaust fan. I didn't cook, except for the microwave, so didn't create much moisture by cooking meals. Moisture did collect on the bedroom windows at night while I slept but cleared up as the day went on. A person exhales up to 3 pints of water vapor while sleeping not to mention what is lost through the skin. The dehumidifier did not run constantly, but will shut off when the reservoir fills. You can connect a hose to some. I never did but was thinking about running a piece of tubing through the floor under the sink next to the low point drain lines, but would need to insulate it so it wouldn't plug with ice. But I could handle dumping it a couple times a day into the kitchen sink or tub.
