I finished mod today, routed it outside at bottom of cover vent after drilling a 3/8" hole, not thru louver. Doing test, fridge is cooling, no condensation yet. Can send pic if desired by anybody. One of my thoughts was if you want to contain condensation in a cup, why make it plastic, plastic serves as an insulator to evaporation, why not aluminum. Also over thinking. It's more stable by not just routing thru louver.

I think the difference in airflow between the slide-mounted refrigerators and the larger ones where the venting can be through the top makes a big difference. Unfortunately, there is just no way to have the venting through the top of the slide-out. It would limit the use to only while the slide-out is extended.

Although my fridge in the 195 is a 6.0 Cf, not 3.9, I think they both work the exact same. I have the drain line routed out the vent cover. It sticks out about 2 inches. My fridge run incredibly cold, so I can say in my case, routing it out does not seem to affect it.

I've never looked mine but I think I'll remove it and reroute too. Thanks for raising the issue mcarter.

Yes, I was probably overthinking it. I need to check the cup again anyway. I may just run the hose outside and forget about the cup.

I don't see it effecting efficiency. Appears mine got into a cycle where the water collected faster than it could evaporate (humidity may have been involved). The interweb has a lot of chatter on the issue. My condensation cup was full to the brim and sloshing over into the reefer bay.

Water cooling would help if it was splashing on the condenser in an absorption fridge too but its not. I doubt you'd see any performance difference if it just gets routed to drip outside. Seems dumb not to do it that way on rpods, other campers do drip directly out.

The water in the condensate cup helps with cooling the line as it returns to the boiler before starting the absorption cycle over again. This is supposition, but I am extrapolating from window AC units where the condensate used to drip on the ground but now is held in a reservoir to splash on the condenser coil. It may not be equivalent,

It will sacrifice a little bit of efficiency, but I'd rather not have the moisture accumulating and rotting the floor.

Why would it sacrifice efficiency?
