<SPAN id=_ctl1_ctlTopic_ctlPanelBar_ctlTopicsRepeater__ctl2_lblFullMessage>Ryan, depends on how big you are building....My crew-cab box has truck sliding windows front and back then in the doors they are some type of windows that slide also but smaller to fit in a crew cab door. What ever you get, let me suggest some sheet metal as a visor over the windows to act as a drip edge....if you don't remember the house, here is the link...

Does your shooting house have 4--wheel drive too?
Actually I did go hunt with a buddy several years ago who had an old junker on the property. He said he decided to clean it out and try it. --Turned out to be a pretty good shooting house--"CAR" The neighbors never knew he was hunting from it.
Now for the Question at hand. I bought 1/4" plexi-glass to put in mine. But I dont want to loose half my space with a sliding window. I am still trying to decide on putting hinges on the top, and letting them fold in. or sacrificing half the window opening with a slide. I know it could slide both ways, but when the deer is running does you may only have a short time to get on him, and all the space you can get.
