Have a 2002 Itasca Sunrise 32V, drove home from Bellingham, WA yesterday through quite a storm on I-5 south. Lots of wind and rain, noted a small amount of drips on the inside of the passenger windsh...
I thought I had a windshield leak last year. After further investigation I found that a couple (one was barely leaking) of the clearance lights up front were leaking and the water was finding it's way down the windshield after dripping into the cabinets above the windshield. Just a thought... before you condemn the windshield, have someone spray the front of the MH with a hose and verify the source of the leak.
