I took a chance and ordered the overhead gun rack. I have my doubts on the head room clearance, but there's little other choices. The bed is too small for a gun case, as I had originally planned. I like the vertical mount design, but hate to dedicate that for the middle of the floor. Can't hang anything over the back window cause now I have the rear panel.
So we'll see how the overhead system works out. I'm 6'1" and so far no bruises on my head. I'll let y'all know in a few weeks how my head feels. LOL!
