Hi, Moose, and welcome! What you are missing is called a "bulb seal" and it can be obtained from J&R - you'll see references to them all over the forum. The technique for installing this bulb seal is also covered in various posts in the forum. It's a bit difficult, and involves separating the two halves to do it.
A "temporary" or "interim" fix would be to place pool noodles or foam pipe insulation (which you can get at any home improvement store) into the crack when the top is raised for camping. These would have to be removed before lowering the top, which is the minor disadvantage to this fix.
The purpose of the bulb seal is to stop drafts and bug entry, so anything that does this is fine.
