"leaking" fridge has caused trim to start rotting

My Norcold came with a drip pan external to the fridge, but inside the exterior vent. I guess the idea was for the water to drip in the pan, and let evaporation take care of the water. However, I was always afraid evaporation would not take care of the water and the excess water would splash out of the pan.

I solved that problem. I just stuck the drain line outside the fridge vent. Now any excess water from the fridge drops harmlessly to the ground.
