We will be living in a Heartland Pioneer QB300 travel trailer starting this fall (october-april) near Valdosta GA. I think that I need a dehumidifier to control the moisture buildup in our unit. Having never did this before, I am asking if anyone has been through this? Our unit is new, and I sure don't want mold or mildew building up on our walls, etc. We have about 300 square feet or around 1600 cubic feet. There will be two adults and 2 cats living in the unit through the winter months. Haven't quite figured out how we are going to transport two cats in our SUV yet, should be a "learning experience". It will be almost 1600 miles and the most the cats have traveled is to the vet (25 miles). I'm wondering how large a dehumidifier I might need, any thoughts out there?
