The dog decided she is too good to go thru it and it makes the cab noisier Nuff said

About the only thing I use my F150 rear sliding window is to throw my empty beer cans in the bed of the truck. If I had a TC I would probably continue the same process hehe... I'm a bit too big to crawl thru the window.
