My 2015 3500 Cab/Chassis with 2017 THOR RV factory install has rainwater leak into cab drivers side, runs directly into dash tight at door, drains into fuse panel and electronics directly below enroute to the floor. Not a river but a drip, drip risking damage to electrical systems. Looks like possible leak windshield gasket or drivers door gaskets.

Not 10,000 miles on this rig but at gross weight could be caused by normal use torsion twisting of frame/body. Any user experiences any model of Sprinter water leaks this position welcome.

Thanks.....

I have read on another forum of a marker light on the cabover wasn't sealed proper or more precise the gasket was installed at all. They thought it was coming from around the windshield or the cabover seal. If yours has the marker lights on top of the cab might be worth a look and a simple fix.
