I purchased this small 25 pint unit at Home Depot for around $158. It's pulling about 8 ounces of water from the air per hour of run time. Set on low fan speed the unit runs very quiet and one can still watch the TV in the background. The unit uses about 400 watts per hour. Adding the TV and cooler I am using about 500 watts per hour and the 500 watts = about 1,500 Btu which heats the trailer very nicely to about 20 deg above the exterior temperature.
I would strongly recommend this unit, or a larger unit to anybody living inside a RV during the winter months where the humidity is above 45% as the high moisture is causing lots of hidden problems to your unit.
