Hoping not to replace the whole unit- the camper is 13 years old, and the Danfoss unit is 3-4 times the cost. I don't plan on having the camper more than another 4-5 years, and it won't affect the resale. I'm definitely going to look into the replacement of the ammonia unit based on the limited response so far. The downside is we leave for 2 weeks tomorrow morning, only one of which I will be at. I guess I can order the replacement Monday and do the install a week from Sunday. I'll just have to ask the wife to rely on ice for the time being.
