I had a Coleman with a ratcheting crank. I was taught that when you see the sides almost taut (not fully taut to the point of stretched), then that's when it's up. There was also a "Release" for the ratchet that then allowed me to lower it. I recall it wanted to come down by itself, but I was also taut to lower it slowly, engage the safety catch, reposition the material, then resume the lowering.
I thought all units did this. I would hope that some kind of "stop" be present to prevent the collapse you describe. Even if it were quiet there should be some kind of a catch or release by the handle. Did the prior owner not provide the manual? I hate when they don't store the thing with the rig - PUT THE THING AWAY EACH TIME.
Maybe a quick call or trip to a dealer that sells Starcraft popup trailers might be possible. Ask for a service manager.
