i had my truck in for regular service and pointed out that there was dirt and grim getting stuck behind the edge of the brake lights and the edge of the tail light that is on the cabin. i asked them to fix it because i thought this was a finish issue as in they had not done a good job putting the truck together. i was told that no, this is how the truck was put together and it is not a problem. you just have to use a toothbrush and wash behind them every time you wash your truck. WTF. it is a poor design for the lights.
