The EPDM (I think it is EPDM) roof on my 2004 Outfitter TC is coming unglued from whatever is underneath it. I see several areas that are lifting up. None are raised more than 1/4" but they show up....
I think I would be concerned... if it is losing adhesion in partial areas it might continue to do so over time.
Has anyone else ever seen a TC going down the road where the roof material in the front is ballooning up as it travels? I have seen it perhaps twice. Not saying that the OP's will do the same or is doing this currently, but it might have the potential to do so.
