In the summer,no problem.
In the summer time the A/C System is the dehumidifier, so there should be no problem.
Winter time is a different story, if you camp in cold weather you need to keep the air moving in side of the camper. You have all of that cold air around your camper on the out side, with the heat on if you try to keep the camper tight you will create a bigger problem with humidity, more and more mositure will build up on the inside on the windows, walls, furniture and any thing else that is inside, this can create other problems over time. What is need is a mix of hot and cold air. The hotter the supply air the more mositure that is in it and when that warm or hot air hit a cool surface the mositure will then condense and now you will have condensation on all surefaces.
With conditions like this the inside of your camper becomes an evaporator just like the indoor coil to your A/C system. The difference between the two is that in an A/C system the condensate is collected in a drip pan and then it drains out of a 3/4 inch pvc pipe and then to a drain, but in your camper it runs down the windows and walls because it is a hard surface just like the fins on an evaporator coil but any other material will obsorb the mositure like curtains, sheets, furniture and carpet and remember mositure is bad for electronics.......This is one reason we do not camper below 40 degrees, there is enough problems with campers with out adding to the list, campers really don't like cold weather as a standard rule.
