Noticed headliner stained near rear slider. Called my service rep Duncan, he said properly 3rd brake light . Before bringing truck in also noticed that the rear floor was soaking wet. Brought truck in to dealer, Ducan set me up with a loaner truck and listened to my concerns. They replaced 3rd tail light , turned back headliner and rear carpet to dry out properly, then reinstalled. Better yet covered under warranty. Duncan kept me advised the whole process. Another fine job. The only problem was some glue residue on the back seat but, Anthony the service manager took care of it himself.
