So this was a factory-installed bed liner? A factory liner shouldn't rattle at this point. I'd either get it fixed under warranty or see if they will pull it and credit you. They may not be willing to pull it and credit you as this was a factory install, not a dealer install. They should fix the rattle under warranty.Thank you in advance for comments! The 12/15/2022 received as ordered drop in bedliner rattles somewhat over rough roads. Seems like I can make it a warranty issue. I plan to rarely use the truck bed & could put a pad down to protect it if I haul anything in it. May never take it off road.
What do you think about having the dealer fix the rattle status - or should I have them take it out & credit the $350 charge rather than silicone or other glue down? Had I known of a rattle in advance, I'd not have ordered it since a quiet ease of handling ride is paramount to me.

However, keep in mind that drop-in liners are subject to rattling. They can be padded and sealed in place but they are a big plastic tray dropped into the bed and are prone to coming loose. This is one of the big benefits of a spray-in liner.
