Don't think I'll read all 8 pages of this, but I will chime in.
Our Monaco has a dometic "Z-door" side by side, and I have NO complaints at all. It will keep ice cream cold (freezer runs at zero degrees always) and veggies fresh (fridge is at 36.)
It came with various fans preinstalled that I hear cycle on and off. Judging from how well it works, I'd guess Monaco got the installation and airflow in a slide right.
It has both water and ice thru the door.
It's big. not 18 cubic foot big, but big enough that even as we look forward to full timing, it is not on my list of things to replace/upgrade.
And when I need it to, either boondocking or running down the highway, it will run on propane.
Back to the OP's question?
If it died, I would switch.
