NeverCold out.... going residential.

I agree -- replace the NeverCold. We just bought a brand new Grand Design 303RLS fifth wheel. We are living in it temporarily (Colorado) as sold our house. When temperatures dipped below 30 degrees, it stopped working. Got ahold of Grand Design and Thedford. Excuse was it doesn't operate under 32 degrees without a cold pack part. The model is a N811FRT. Let's see -- I bought a fifth wheel with an Arctic Package and duo pane windows. You think I would want a refrigerator installed that doesn't work under 32 degrees. Well guess the manufacturer thought so as had to argue with them to get it fixed. In the meantime, kept food outside in a cooler for two weeks waiting for weather to permit us to take it to Grand Junction for warranty work. Oh, before took it down there it mysteriously started working. Had the cold pack installed -- basically heat tape on the back of the refrigerator. Have to uncook it in warm weather so doesn't overheat. Well all was fine until two days ago. We aren't talking below zero weather! At night its been around 20 degrees and in the daytime 45 degrees. Well it stopped working again and I'm back to a cooler outside. Brand new rig. Brand new refrigerator. And, it doesn't work! I'm shopping right now for an electric apartment refrigerator. My one question is how much space do I need around it? I've read 3" each side and back. Depth seems to be the primary issue to allow for this much air space in back. There are top and bottom plastic vent on our rig for NeverCold refrigerator ventilation. The refrigerator is on the side slideout. Does that provide enough back ventilation?
