Another roof question

[Ambler]

When lowering the roof (slowly) I've noticed one side always lowers faster then the other. By the time the roof is about 6" from completely down, this is quite noticeable. Of course it all levels off when lowered fully.
Is this normal?

Yes quite normal, mine has done it all the time
