I hear ya! After a couple of spills, we called it quits on the salty stuff. Just happened to run into a fellow camper who turned us onto the Eva-Dry units. Like the fact we can use these a long time, hopefully!

The a/c should operate to where both the temperature and humidity is comfortable. An oversize unit will cause the unit to operate in short spurts of on and off. A properly sized unit will run until the thermostat shuts it off and hopefully the inside air will be properly conditioned, both temperature and humidity wise. Too small of a unit will mean it runs non stop, never reaching the off set point. How does your a/c operate and which unit do you have?
That is not what I said at all. A/C units are controlled by a thermostat and shut off based upon temperature. That does not mean excessive humidity is removed when the thermostat shuts the cooling cycle off. I have a three ton heat pump in my house. If I ran it long enough to lower humidity to acceptable levels I would be shivering. I run a separate dehumidifier as well as the heat pump to keep humidity levels acceptable. It all comes down to the fact that the climatic conditions vary in different parts of the country. If I camp in the northern states, the A/C does an acceptable job of keeping the humidity down. If you doubt what I am saying, might I suggest you camp in the Florida Keys in August.

As Bob and Carl explained, sometimes you need to remove moisture even after enough heat has been removed. Since a dehumidifier works by cooling air to the point that the water comes out by condensation, then dumping the heat right back into the air, running the A/C plus heat does essentially the same thing. A dehumidifier is much more efficient, because it puts the heat taken out of the air back, while running A/C and a heater means throwing the heat taken out of the air away, and using more energy to replace it.
