You are correct the parts left in the box is not much but probably the most time consuming. A bunch of sheeting on compound curves, like the sides and the turtle beck .Looking good, you will run out parts to glue on soon!
I do the same, tape it together tight on one side, open and add glue, then pull it together tight and tape that side.I've read recently that some people tape the top of sheeting after gluing and wiping. I tried it and it works, not sure what it does but the people who posted it were well respected builders so I do it now.
