We sometimes stay a month or longer at some sites and the Fridge/Freezer ices up. My better half went to defrost the fridge the other day and used her hair dryer. Bhadda B........Bhaddha Boom!!!.... the fridge was defrosted in under 20 minutes; little muss and less fuss. I mentioned it to our neighbor and she said she had started defrosting her fridge a couple months earlier using her hair dryer (and they have been RV'ing full time alot longer then us). We have never read this as a 'tip' in our experiences and I felt somewhat chagrined that we had never figured this out before this. I assume some of you already have, but nontheless, feel compelled to post this on the forum for those who have not. Works like a charm and is a major time saver.
