I think I'm going to try and remove the glass from the frame and replace it with two 15" pieces that leave an opening in the middle. An actual slider isn't really needed. I'll seal the gap around the sliding section of the cab window. I really want the exhaust fan on the topper to also cool the truck when it's hot out. I need to pull the clamps to to do this and I'm looking to redesign my my bed layout so it's a good time to rethink the mounting setup. Direct bolting might clean things up a bit.I really wanna replace the topper front window with one that can open too. Mainly if I ever needed to go from bed to cab. Yes I'm skinny enough to make the climb lol.
