I have a 2018 redhawk 31xl. The last two camping trips I have been getting excessive condensation in the refrig area. I always run the refrig on electric. The ceiling of the refrig section is literally dripping. The excess runs out the bottom when I open the door. The refrig and freezer sections seem to be operating normally. I keep the system on the middle cooling selection.
When not using the RV, it is plugged in with the refrig off and propped open.
