Hi there. New owner of a 91 Winnebago Warrior V6. At the cabover bed, if I press with my hand against the side wall near the upper left and right corner, it seems to me that a little bit of light appears. I can't see outside of course. The sidewall doesn't appear to be soft and I see no evidence of leaks that have bled down into any of the bed area. When I inspect the roof or side wall on the outside, I don' see any evidence of repairs and the caulking seems good, but it sure seems to me that this implies that the seam is loose. My theory is that by pressing on the wall, the sidewall might actually be moving into the seam area there is the vinyl inserts. This rig has spent almost all of its life stored in a barn when not in use, so it is possible that there is a pending "leak" that just hasn't manifested itself because it isn't parked outdoors. If so, I'd like to get on top of it. Should I be concerned? Do any others see this? Apologies - a newbie. See attached photo
