Water leak in side fridge vent, or roof fridge vent?

[Jandj1026]

2 days of heavy wind and rain have invaded my camper. Water was in the bunkhouse at the rear of the rv on the floor. Some of it soaked up into the wood that makes contact with the floor, about 2 inches up, causes the particle board to puff a little. Never had any leaks before. This was a puddle about 6 ft. long on the floor. coulld this have blown in the fridge vent on the side of the camper? I can't find any other way the water could have came in. It was wet under the fridge once I took the panel off. Anyone heard of this happening? I am new at this so I dont have any ideas. Thanks in advance for any help.
