Folks, need a steer...my pop up roof - rock wood premier circa 2004 hand crank - is stuck fully up. The back lowers but the front only goes down 2 inches when it seems to stop solid. As if the 2 front poles are jamming against something. Any ideas on this? Same thing happen to anyone else? How do I fix this? Currently up on my driveway but want to leave for BC on Thursday!!!Any help appreciated
