The angle that you are seeing in the slides is supposed to be that way. The design keeps the slides from leaning out during turns, otherwise, you would see the slides coming out at the top when on a turn. Older rigs used rods or whatever they were called that you would have to wedge in at the top of the slides inside after they were pulled in, but this is not possible with the many slides making it impossible to access the slides once they are all pulled in.
