Moisture in underseat storage compartment.

[acasey]

I have a 2015, 1500 Laramie crew cab. Just recently I noticed moisture inside the compartment under the back seat on the driver's side. Has anyone else had this issue. If you did, where did you find it was coming from?

In order of most common to least: third brake light seal, rear cab vents, sliding rear glass drains, xm/gps antenna seal.
