Ok I've searched and searched on here about my problem, but haven't found any answers. I bought my PUP about two weeks ago and have been "fixing" it up. Today I was working on the roof and had the frig going all day and it never got cold. When I first bought it I left if plugged in for about 3 hours and you could tell a noticible difference. I am trying to run off AC because I'm not quite sure about the propane. I have a friend that is going to bring over a sniffer next week to make sure I have no leaks on the propane. Until then I'm kind of leary about using the propane. The camper is a 98 coleman. Why would it work one day and not work anymore.. Should I hear any noise while its on? Bc I dont hear anything. I really dont need the propane feature b/c my wife won't "boondock camp" but is there anything I'm missing. My camper is level also. I'm thinking of just disconecting the gas lines and putting a walmart frig in thats 110. Whats your thoughts on this? Thank you for your any info you may have.
