Our refrigerator went last weekend while we were camping. We noticed a green fluid when we took the outside vent off and when we turned the frige off there was a horrible smell of ammonia. So my question is.....do we order a new one and try to replace it ourselves, or do we just replace the cooling unit? And if we take it somewhere....where do we take it? The few dealers we have in the immediate area don't have very good reputations. How about Campers World? They are about an hour away? Any help would be greatly appreciated.
