Well I guess I spoke too soon. We got a leak over our door last week while we were in the Chicago area, but we did have 5+ inches of rain that night. We have a appointment with Mentor RV for next week.
That's where all our leaks have been. None on the other side or to the rear.
Odd.
Once it gets in, the water spreads under the interior angle vinyl piece between wall and ceiling toward the front of the trailer and the clothes cupboard on that side.
