2003 Monaco Knight 36 PST Slide Adjustment

[Mile Marker 42]

Does anyone have a similar coach that can help me adjust my rear slide. I think I just figured out why it is the only slide that leaks when it rains. If I am inside looking at the slide, it leaks on the right rear. The top of the slide needs to go out at least another 1/2+ of an inch and I do not see where that adjustment would come from. The only adjustment I see is at the bottom on the outside center of the slide bottom. There is a bolt with a nut on it. Does that determine how far the slide can come out on the bottom or how far it can go in? In a perfect world, I'd like the top to come out 1/2+ of an inch more and the bottom to go in about 1/4- of an inch more when closing. Does anyone here have any knowledge on this that might help? Beers on me if you are anywhere near me:-) Thanks in advance.

BTW, this is a bedroom slide.
