Domo - it's a 2007 Coachman Mirada. Only had it for one year.

UPDATE: took the rig to an RV service center and they said no soft spots on the roof, but the drivers side radius has soft spots (I guess that means it's lifting up from the lauan underneath). RV service center suggested replacing radius on both sides to be safe (of course). So I don't know what caused the water leak inside unless it had something to do with the vent install. Gonna have the room pressure washed and resealed and maybe wait to do the radius later.

If you spray mist stained area with bleach it should remove stains, may take a couple of applications, hold a tray or carboard under misting to keep it from hitting areas under misting.

About the only way you can determine where the leak is without removing the roof is to take it and have a pressure test done. They use a machine to pump air into the rv and then go all around with a mister ti see where the air bubbles occur. If no bubbles around the vent...the leak is somewhere else.

On some mohos (such as my Dolphin) the area under the roof fiberglass cap side radius is hollow (just driver's side in my case) and may even have wires running down it. Earlier threads I have seen on this forum said they will feel soft there and it's nothing to worry about. Not sure if that's true in your case but yours looks very similar to mine, though your low spot where the water is collecting is perhaps a bit more pronounced.
