Bought our Windjammer last year only used it for a two week trip, then it had to go back to forest river to replace the entire left side wall due to a cracked above the bedroom slide out. So we didn't get to use it much. I took out the filter and let it dry when I winterized. I just last week re-installed it. It still looks new. Wish I knew about the freezing. Should be OK I hope? Maybe I should run a little bleach through the system?
