Panels Leaking?

[horkyroj]

Well, the far back corner of my 1998 Coleman Mesa has water damage on the OSB.  I ran out to the storage place yesterday and checked after a good rain and yes the OSB wood is wet.  So now I have the fun task of figuring out how the water is getting down there.  I know the water is not making it in the roof since nothing inside the pop-up has any water damage or spotting.  So I am thinking it is getting in between the side-panels somehow.  The Coleman Mesa has aluminum sides and an ABS back panel.  So my question is what is the best way to go about finding this leak and fixing it?

On another note, what is the best way to store a pop-up tongue up or tongue down?

If the fridge is running, store it level.  It shoudn't do any harm to store it level all the time.

Having said that, in winter I store ours tongue low.  We have a front storage bin and the top of that slopes forward slightly.  I don't want to eliminate that slope, so I enhance it by storing tongue low.
