Geof mentioned his freezer, that reminded me of what I was told in Elkhart regarding refrigerators.
When I was looking at buying a surplus electric/propane fridge, they told me that Lowes sells "Katrina units" Basicly replacement refirgerators for all those FEMA trailers still out there. he said they sold for under $300. I just did a quick search on Lowes website, I didn't find that particular unit but I did find the perfect unit for DIY rv builders! check out this "Compact Kitchen"
