Just clean your blankets wash or dry-clean and put them in plastic tubs with lids or in garbage bags and squeeze out all the air and seal them up. They will be fine in the spring. Air you pillows well and do the same to them.I use the Damprid buckets and they work great... about $9 a buck and last all year. Also if you have a propane refrigerator that is causing a lot of moisture. If you do have electricity I would use a dehumidifier and be done with it. However you'll probably have to replace your blankets, pillows, and other items like that.
If it smells like that, it's an authentic camp.My camp has had that Smell for as long as I can remember, a combination of musty, wood and coal smoke. Whenever we come home everything we took has that odor. I kind of like it. It reminds me of better days !
