I have a 2013 F-150 SuperCab with the 5.0 and a towing package. LOVE the truck. I am running a toneau cover and up here in Canuckville I get snow swirling behind the rear window and crating a drift. This of course freezes & thaws and falls down between the cab and the box. The heat from the cab freezes this and I get loose chunks of ice trapped in there that rattles every time I hit the slightest bump. Anyone else have this? Anyone else have a solution? I am thinking I may paint a pool noodle black and wedge it in there just below the top of the box to try and keep the snow out. Like I said, it is a small thing but the only way I have fixed it thus far is to turn the radio up.
