I'm not sure if anyone else is experiencing this but I appear to have had a rodent of some type crawl up into the roof of my truck between the headliner and outer aluminum shell and stash some acorns or something like that. Every time I turn on a curve they roll around from one side to the other and it is driving my nuts, no pun intended. I don't know how to access the area without doing a major headliner removal and was wondering if anyone else is dealing with this?
