Reefer Condensation Drain

I have been working some RM 8501 issues with my 2015 178. The reefer is included in the slide.

There is a condensation drain at rear of reefer, the drain tube goes into a plastic container at the bottom rear of reefer. My inclination is that retainer cup is designed to evaporate with heat at the rear of the reefer. My retainer is full and the floor of the reefer compartment is damp. Obviously the plan to have that water evaporate is not working. As you travel or use the reefer that cup is filling and when full is overflowing into the bottom of the fridge compartment.

My plan is to extend the drain line outside the lower louver on the reefer bottom vent. I don't want condensation staying inside the reefer compartment. I already have mold forming. Because my reefer is mounted in slide, it can't be routed out bottom.

Other sites have addressed this issue and this one may have also done that. Open to discussion, but don't think this works as designed.

Originally posted by StephenH On mine, the condensate cup cracked. I glued it back together and so far, it has been holding. If it fails, I'll run the tube out through one of the openings in the grill so it just drips on the ground. It will sacrifice a little bit of efficiency, but I'd rather not have the moisture accumulating and rotting the floor.

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. 

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.
