Ok, here is a question put out for opinions. Slider Rear Windows...good? Bad? Do they help in venting the truck? Do they increase wind noise? The reason I ask is because my 86 presently has a one piece rear window in pretty good shape, but I also have a slider that I've been thinking of putting in. I've never had a truck with a slider before, so I don't know if it is really worth it. So let me have it. What's everyone's opinion?
