I have a small leak on drivers side, looks to be coming in around the side panel from under dash. I hear this may be common anyone have any experience with that? Thanks guys appreciate any helpful feedback.

Welcome from VA, cool truck!
The leak is likely coming from your cowl.
Many different ways to go at it that I have seen several members describe on this forum.

Welcome from Austria. Nice truck.
Could be the windshield weather seal or the cowl. Test it with pouring water into the cowl.
