2011 Auto trail Scout showing damp behind drivers seat. We took the dinette window out and could see evidence of water coming in all around where the decal was. Decal had been put on and window sealed over it. With time the decal had wrinkled a bit around the window and split in places. This allowed water to get in between decal and van. There was no sealant attached to the van where the decal was.
Have posted as might be worth checking if you have decals that are fitted under a window if they have split.
