I’ve recently acquired a 1980 Serro Scotty. The trailer was completely destroyed by water damage after sitting for years. I completely removed the passenger side wall and used the skins as a template to cut out new plywood walls. I know you cannot screw into the edge of plywood and that has left me baffled as to how to join the roof to the new walls. Any help would be greatly appreciated. I will attempt to add photos for reference in the thread. Thank you!

After some research I've found that what I'm describing is replacing the edge board. I've seen threads on how to remake the edge board by gluing strips on 1/4in plywood together. I still am unsure as to how to attach the edge board to the plywood wall without using any type of fastener. Still wondering if there is any alternative method to joining these components without having to rip dozens of strips on plywood on a table saw. Thanks for the help!
There are several things that you can do. The first is new roof metal and bend over the siding. I don't like butted metal because of the leak issues. You could then replace the edge L trim with J rail. The screws go in thru the side into the plywood and ooze the putty appropriately.
Another thing to do would be to add wood on the inside of the ply, making the edge wider. These would be between each rafter, glued and tacked. This would give a stronger edge with less movement on the road. Scottys are known to leak at the metal butt, hopefully the wide edge would help prevent that.
If I remember my Scotty correctly, I think the edge L trim screwed down thru the roof metal. The extra wide edge would give plenty of purchase for the screws.
On the 69 Scotty the edging was glued and stapled to the plywood wall edge. I used 1/4 strips also glued and stapled, stacked one strip at a time to achieve 3/4" to match up with the horizontal 1X4s. Some judicious belt sanding took care of lumpy spots. I also tried one of vikx' tricks and curf-bent some 1xs and filled the curfs with thin strips of wood ripped on the table saw and glued in.. tedious but made for a nice solid surface to better hold fasteners.
