Roof Raise Plan with question about back supports. Video!

[Jipner16]

Pretty simple question in the video and showing what's going on with my roof raise. I have the transit/charter window set up so I think the supports are slightly moved around. I am planning on going up 20 inches. Any idea on what the triangles in the back are and where I can cut them at the bottom?https://youtu.be/3UEk07xvfFI

Actually because the video is unlisted I can't see your comment
