A couple months ago we had a small short hail storm while the RV was in storage outside. No biggie.
Then as we were loading the RV for a long trip in our driveway we had a huge rain storm - 6 inches in 30 mins - I'm not exaggerating.
The next day we were putting new sheets on the bed and found a damp spot on the mattress but assumed it was just a fluke due to the massiveness of the rain a couple days before.
So, we leave home and the first night on the road it started raining during the night. And we realized it wasn't a fluke. Water was dripping on the bed. Not fun during the night.
The next day I hunted around and found a tiny hole in the edge of the plastic roof vent in the bedroom. It was a BB-sized hole. I had not put a cover on that vent because I always planned to replace it.
We were able to caulk the small hole for a couple of days and then changed the vent for a MaxxAir fan a couple days into our trip.
When I replaced the vent I was surprised at how thin and fragile those vents are. And it was pretty brittle too from a year in the sun. So, check the vents when you check the roof.
