Our 2004 Itasca Meridian has several black marks in the ceiling fabric. Two of these marks are above the pillow area of the bed, two more above the foot of the bed and another over the toilet room door. They look like dirt or oil that has settled down from seams in the ceiling since they are aligned in a row, from left to right. Has anyone else with recent Winnebago products experienced this?
