Sorry I know I’ve been posting a lot with little issues I find in my new truck.

Had a new thing happen today. I was backing into my driveway and when I stopped, while still in reverse, I felt a thump. It was like something rolled in the bed and hit the cab. I knew there wasn’t anything in the bed so I pulled forward then backed up again and it did it again. I thought maybe the spare tire had come loose and was swinging under the truck. I got out and inspected everything and couldn’t figure out what the heck was causing it. I’ve had the truck a couple weeks and it’s a 2018 with about 20k miles on it. Any ideas?

 

Had that happen once. Was my rear seat coming down...
