Hi, This is my first season with a (new to me) 1999 Flagstaff 620, and I am a little curious about some of its inner workings. This pup has a small fridge that can run off of 12VDC, 120VAC, or propane. From what I've read, the 12v option is not usually a good idea as it kills batteries pretty fast. I've used the propane option over several 3-day camping trips and it seemed to work great. Cold within minutes. Almost icing, which I don't mind. I've been camping since Friday, and plan to do so until next Friday, so I've been using the 120v option to conserve propane. It seems as if the fridge is not getting as cold as it did with the propane. Granted, it has been 90+ degrees F here, but it literally took the fridge a day and a half to even feel colder than ambient. It's a good thing all the food was packed in a cooler full of ice. Currently the fridge feels cool, but still not as cold as I thought it should be. Is this a normal situation? Is it the ambient temps affecting my fridge's cooling ability, or is the 120v operation somehow less efficient than propane?
