Ammonia Fridges, read an interesting piece a while ago

I've got a side by side Domectic in my 40 foot 5th wheel that setting on my rV lot. It's 2003 model, and yes it still works. But just before I left to go on this trip I on it was starting to act up (like not holding temps). So when I return I'll probably take it out and install a residential unit I found at Home Depot that'll side right in. Just have to fill in on the sides, and some trim on the top.
