Water ingestion in engine on 2011 Tiffin Phaeton 36QSH

Your coach has the air intake at the upper left (driver's side) corner of the rear cap. There is a large diameter tube that runs down the inside wall of the rear cap, turns and goes into the air cleaner. Typically, at the bend in the tube as it turns toward the engine is a drain. Many have a "duck valve" type rubber drain. Looks like two large rubber lips hanging down. It's suppose to drain and water coming in through the air intake. Check your coach for that drain valve.
