Has anybody tried installing a 3 way Fridge on the 320 CS-S in the rear? Was there easy access to the propane line? How did it perform? What model did you use? Size etc. Thanks.

    My understanding is that it’s impossible to properly vent a propane fridge in a clamshell. Why do you want to do this? What’s the problem you’re trying to solve?

    Well it seems propane is less draw on the batteries, We have a 22 320 CS-S Boondock but no Lithium (Yet) Until I get it better set up to run longer on a 12 volts. I do have Bluetti 200 watt solar panels but for some reason I don't see an external plug to plug the panel in. We almost never go to campgrounds so I need to keep an eye on the batteries. The fridge that comes in the clamshell is almost a laugh for how much it will hold. We do have a 12V ARB 72 qt fridge that we keep in the Jeep with a Bluetti power station.

    Especially since you already have a very efficient ARB cooler, do the lithium upgrade instead of the propane/3 way route.  No regrets.  You can hook up an external 12 V port to plug in the ARB.  Is it a Norcold or newer 12 V frig in the galley?

    You are right about a 3-way on propane when boondocking not drawing much from the batteries. But fortunately, a lithium upgrade is much cheaper then it used to be. And that upgrade would be much cheaper then rebuilding a CS for a 3-way. You can connect solar cells directly to your battery (s)

    Buying 100aH lithium battery would be much, much cheaper than buying and retrofitting a 3way fridge, if it was possible to safely install a 3way (I'm pretty sure that it's not). You can also add a controller for your 200w solar panel. 

    But if you already have a 72qt ARB + a Bluetti power station + 200w Bluetti panel I would just use the ARB for keeping food cool and skip the T@B fridge altogether.
