We are getting ready to head out for the weekend, and my husband was starting to lower the roof and it won't move. When you turn the crank it swings freely. We've had it up for a few weeks because my kids have been using it for sleepovers, but we are at a loss to get it down. We are fairly new pop up owners and haven't even towed it anywhere. When I Google the issue, I'm overwhelmed with the terminology that's being used. I also can't find someone who's had a problem with this particular camper. PS, I called our local RV service center and they were less than helpful, so I'm feeling pretty hopeless with the situation.
