Just got back from the KOA in Cherokee NC, great place and the weather was great. Anyway, I attached my filter (forgot name but it was blue, long and good for 3 months disposable kind). well we have only used it once in April and it doesn't work any more. We are going to the keys in a few weeks any suggestions. On another note, the little white curly hose that is attached to my drain of my refer is dry rotted. I have to take it to a local RV place to have it replaced and they said it is common. Any suggestions on preventive maintain? it is strapped to the coils on the back of the refer which gets warm but is not as hot as the rest of the parts.
