We recently purchased a 2003, model 2023 in excellent condition. I've just got it out of storage to get it ready for camping soon. I've encountered a problem that I hope you can help with.

I think the safety latch snapped into position when the top reached it's full height, but it will bleed down slowly. Any ideas on what might be wrong? The owner's manual doesn't address this. Any ideas will be greatly appreciated! Thanks
