Not sure where to post this. We have been driving in rain off and on the last few days. I have noticed when we stop I have some water dripping from the black plumbing fixtures on the OD side. The leaking is right around the plumbing where it comes out the bottom. After a while it stops. I have gotten under the RV and pushed up on the black bottom covering and nothing runs out. I have sealed up the black bottom covering everywhere i can find and used expanding foam. No leaks in the RV and nothing comes out the DS.No water comes out around the black and gray water plumbimg if parked and its raining--only when moving......
