Im still not sure how Im supposed to access the backside of the trim. You can see the clips in the area where the spare tire is. But they are completely hidden behind the cargo area sheet metal on the driver side and even on the passenger side when you get closer to the cab area.

Unless someone can show me how those panels are removed easily Im inclined to just cut a couple of access portals and then MIG them back down after.
