Hey could use some help here. I am in north east Washington in 36' 5th wheel. Never winter camped before so have dine everything wrong. Left grey water tank open and now drain hose frozen and also frozen at connection so can not disconnect to use other hose. Did not put any skirting around trailer-did not know about it-now money real low, can not afford fancy or thick skirting material. My holding tanks do have heaters. Any ideas on how to fix my problems. I am 65 year young lady trying to do this on my own but failing miserably so far. Love the rv life but just need help to get thru these problems. Thanks.
