The Clipper is a diesel pusher so thought it might have something to do with that. We assume that may be the culprit but what is it and what do we do? When we open the cargo door and look up, this vent is above that metal floor so can't see what it is but notice rust along the metal floor. There is a large black hose that goes up into that area so it is probably a vent for that but this is not a good situation. HELP!!
I'm sure you found your leak by now, but just to confirm, "THE VENT AT RIGHT REAR IS THE AIR INTAKE FOR THE CUMMINS 300".
Yes, if the wind is on this side, water will enter the intake tray.
A SIMPLE SOLUTION IS TO DRILL 2 SMALL HOLES IN THE OUTSIDE RETAINER SO THAT WATER CANNOT ACCUMULATE OVER THE INSIDE LIP and possibly fill the airbox mounted on the inside wall behind the lower drawer in bedroom.
