I eat lunch in my truck, lately i have been hearing a random tick or knock. It sounds like a twig or tree berry hit the roof.

Anyone else have this happen?

Came here for this...I have had my suspicions, thought it might be the bed cover strap blowing around in the bed but certainly sounds like its in the roof

I hear the same exact noise. Actually 3 different noises. First one sounds like an acorn hitting the roof. Second one sounds like a strap slapping between the cab and bed. Third is a clicking or knocking coming from the rear window area

This happens to me where it sounds like something falls into the bed. The vents on the back of the cab have these plastic covers that pop out with air pressure changes. That’s what was making the noise for me, it was hot outside and I was blasting the AC. You can see the flap move if you are looking at it and shut the back door.
