Re: regerator problem and questions
First off don't go with Norcold. They're terrible- I know I have one myself. One problem is if it's hot it won't cool- I fight mine all the time, and have to load it with already cold food at night when it's cool. If I put too many warm drinks in at once, it will never cool- it just goes belly up and is luke warm the rest of the trip. I can't wait to replace mine either.
Second, the 3-way need hole cut in the wall, and a vent stack (chimney). All you really need is a two-way (12v/110v) or even a 12v only.
Install is pretty simple if you stay the same size- what would help is to know what size you have currently. The 2.5cf Norcold has a little curved metal plate that is the "freezer", where as the 4cf has a separate little plastic door on the freezer, inside the main fridge.
I'll let other people recommend which brand to buy, I'm interested myself!
