For trucks, having a glass roof is almost essential for seeing if you will fit into a parking garage.

If your truck is that tall, I suggest measuring it and recording the height. After that, you'll find that just about every low-hanging garage, drive-up, bridge, etc. has a height listed. Over 9.5'? Don't try and drive through the Arboretum, as the signs will tell you.

Opening the roof...

That's a sunroof, not a panoramic glass roof being discussed.
