15 xlt I have had it for a month when looking at the inside of the tailgate there is a hole in the upper plate I have the factory spray in bed liner. I am worried about water and dirt getting inside the tailgate is this a missing plug or all trucks have this?

 

Can you post a pic?

 

Click your post edit button an go advanced button an navigate but U may need to make a few more posts before U can do pictures. There are some blank holes in the box.

 

sounds like the hole for the bed extender retention pin. Used when the bed extender is closed and in the rearward position.

 

The tailgate has holes way in the bottom to avoid any water retention.

 

here is a picture of the hole

 

No hole on mine, but then again I have a huge hole on the top of my tail gate that probably lets in a lot of water where the tail gate step is.

 

I noticed mine was that way last summer a short time after buying the truck. I asked the sales rep, he didn't know. The next time I needed to go by the dealer I walked the lot and saw that they all have it. Don't know what its for, though.

 

Go to your True Value Hardware store with a ppic and measurement of the hole dia and pick up a rubber plug.

 

I noticed the same hole on mine. I asked around and no one could tell me why its there.
