Hi guys, So i'm picking up a Norcold 3 way frige tomorrow from a guy parting out a 99 Fleetwood PUP. I have a 93 Coleman Destiny Royale which came with no refrigerator from the factory and want to install this unit into my PUP. I have a few questions for everyone here in regards to this installation. The first question is about ventilation. Like most appliances, I would assume this unit will require me to cut some kind of vent into the side of my PUP...I don't know if this is true or not being I plan to only use the frige using electric both AC and DC, no propane. Do I need to put a vent? The other question is about the functionality of the frige. Does the frige require the propane to be hooked up even when in AC or DC mode? Or will the frige work without any propane at all as long as it's hooked up to shore power, generator, or battery? I know a lot of you will ask why I don't want to use propane, but i just like the idea of not using propane inside the PUP for safety reasons. Thanks in advance for your replies and happy camping!
