This diagram is what I would think, but not finding this so far.
After the next rain I will bust it all out, hail mary.
It does not seem to be like this diagram. The glass seems to be behind the outside of the frame, and a middle ridge is in place making two inner channels, not the one in the diagram.
My guess is that the glass is built into the frame, so I have to pop it off camper, then unscrew where the frame meets itself screwed together, pry it open and wedge out glass.
Florida is in there somwhere. From the diagram, the glass might be below the black line (frame), not over it, and the FL gasket between glass and black line.
Looks like Thurs afternoon or Friday clears up from rain so will pop it out then unless better ideas abound
