This year my truck has been smelling stale for about a week after washing, At first I thought it was just in automatic car wash but now its even wand wash. I did have the front windshield replaced is there a place there is could leak? or in the back where would a person start looking? No Carpet seems to be wet anywhere in cab that I have checked. Any advice?

Look under the back seat all the way to the rear cab wall. The 3rd brake light is a known leak point. The floor would be wet there or in the storage pockets under the rear seat if it was leaking.

If this started after the windshield replacement, you'll need to look all around the front and see if there is anything going on there.

There are a couple of vents on the rear cabin wall, that disintegrate. They cost just over $5.00 each. Those and the third brake light gasket are a start.

Does your truck have a sunroof? If so feel around the pillars and around the top. I had a 2010 ram sport and it started leaking around the sunroof.
