I converted to a 3 way from an ice box. I got the 3 way fridge from someone who pulled it out of a fwc because it wasn’t cooling well. That person replaced it with a compressor and loved the difference.
In my opinion it’s hard to properly vent a 3 way in a pop up camper so that the fridge cools well. An upper and lower side vent doesn’t seem to vent right. The air just doesn’t circulate well with 2 side vents.
I was able to vent straight up through the ceiling in my hard side pop up and the same fridge that didn’t work in the factory fwc install worked great for me. Seems to freeze my milk even camping in 100 heat. I’d definitely have a 3 way that works well rather than a compressor with all the batts and solar that has to go along with it.
That said, I do think compressor fridges generally work better in pop up campers due to space restrictions.
