Damp plywood front roof cover 2009 Jayco 1206 ser

I own a 2009 Jayco 1206 series pop up. I recently noticed some water (after a rain) on the upper part of the canvas close to where it is sewn into the underside of the roof. I also noticed that the plywood under the front part of the roof was damp. I am trying to figure out how water could have dampened that part of the underside to the front part (curved portion) of the roof. Perhaps the camper was leaning just enough for water to drip into that area?? I checked the seam at the most bottom part of the front of the roof line on the exterior and it looks like it could use a bead of sealant along the metal strip but nothing major. Then again, maybe it is enough for water to seep through to make the bottom of the plywood under the curved part of the roof to get damp. A closer look of the plywood shows a slight dried water mark at the bottom edge of the plywood.
Any feedback would be greatly appreciated as this camper has always been dry and I want to keep it that way. No problems with the interior..this is just some water buildup on the underside of the curved part of the roof.
