Well, not really leaking, more so accumulating water on the inside. The left and right carpet shelves near the back will get wet when it rains but the rest will stay dry. I’ve sealed all the windows real good with silicone and I can’t seem to find how the water is getting in. Any ideas? Might be that the hatch has a little hole where the corner hits the bed, but the hole is undercut and not near the carpet. Could also be the holes from the wood roof rack the PO installed. Might take it off but it is perfect for my canoe.

Any other ideas?
