Hello all,
Just figured I'd post my findings:
Went for a couple night getaway in Grand Forks ND, and was the first time that my 2018 has been outside overnight. I received the truck in December of 2017 and has been in the garage every night since. There was a thunderstorm that came through, and lo and behold, the drivers floor mat was full of water when we went to leave the hotel this AM.
I saw drips coming from the drivers grab handle screw covers, so I assumed it was likely not the 3rd brake light, and was either the sunroof or the satellite radio antenna.
Drove 2 hours home, and water very sporadically dripped from the screw cover onto my knee. Got it home and investigated.
Pulled the headliner down a bit and found the one 10mm hex bolt that secured the satellite radio antenna, and loosened it. Water came from inside the antenna perimeter gasket. Bingo (fingers crossed).
I simply used RTV silicone on the INSIDE perimeter of the satellite radio (shark fin at drivers front of cab) gasket, and the very small square shaped foam gasket around the wire/bolt provision and bolted it back down.
While I was at it, I folded up the tonneau cover and sealed the 3rd brake light the same way.
Just a piece of info for anyone with newer trucks that haven't discovered this yet. This is the first "quirk" of this new truck (aside from hill decent control not working properly, but is far less concerning than water leaks) and was an easy fix. I'm a self employed diesel mechanic by trade, so diving into this doesnt bother me. Definitely not worth my time to drop off at a dealer, that's forsure!
