Help needed for Roof not raising all the way.

I measured the 4 corners and none of them where the same. So instead of trying to adjust all the cables myself, I took it back to the dealer (turns out we have an extended warranty on the whole camper; glad we bought that). They replaced a pulley wheel that was binding in one of the arms and adjusted the rest of the cables and now it goes all the way up ??yaaay! I also just discovered that the level we attached to the side was off a bit, about 2" at the tongue so that may also have contributed to both the roof issue and the door being very hard to attach to the roof at the top. Hope this helps someone else.
