Motorhome Leaks

The 1988 Itasca Sundancer motorhome that I live in has multiple leaks. My guess is that it could handle 1 inch of rain, but not 2. The latest leak developed at the front roof hatch. And it was like a hemorrhage. Looks like I'll have to take a chance on sealing the roof very soon?

It's got this grey stuff up top that's like a ridge on the front and back. My roof is metal, but I'm concerned about the fiberglass body it's also adhered to. My thoughts now are to try getting the back one off. That way, if something goes wrong, I might be able to use some long sandbags to temporarily seal it? I may even be able to redirect the water flow temporarily?

5th Leak - Motorhome

The motorhome just took on its 5th leak today. The laptop got some of it. I have its keyboard upside down on a towel for the next 24 hours as is standard proceedure.  I also went up on top of the roof and used a broom to get the pooling rain water swept off. There was quite a bit near the front roof hatch where the new leak is.

Two days ago, I adjusted the level in under the rear right of the motorhome. I barely increased the height back there. That might have been what caused the water to pool at the front hatch.

Assuming that it rains when its colder in the day before, I'm just waiting for a string of 70°F days to reseal the roof.
