Thanks for the help in advance.

Oh, I do not have cab marker lights, and I do have a sliding back glass.
Welcome aboard, the water leak crowd.

Yes, there are loads of areas.

First, CHMSL is the most critical; get the new gasket.

Next are rear cab baffles, also known as exhaust vents.

These are behind the rear seat backs, and the rear seat back needs to come out to replace or pull the bed back.

In the new, improved part, there are 2, which are replaced with the new part.

Next, slider water drain holes, a clip that holds the slider cable in place must pop out, and a slightly open slider to remove tension.

Under the clip are water drain holes that drain to the outside, two holes. Grab some .060 sting from your line trimmer and poke through the holes.

They exist outside; notice the gap in the rubber seal on the outside.

Make sure no slime is plugging that area up, either.

You may also have a broken butyl seal along the top of the window glass; water spraying will reveal that.

Also, there are drip stains on the inside, but with water in your truck, you will have lots of condensation, which may appear on the glass and run down.

Other items include sunroof leaks, but the rear stop lamp and cab baffles are your priority!

With body computers and networking, we can have water leaks and get them fixed.

Pull carpet to dry or peel back, lift, run a fan, open doors, etc.
