What could possibly go wrong?

Getting a 55kg tent off the top of Defender 90 roofbars that are 2m10 off the ground. if I could get it in the garage I could sling from the rafters. But it won’t go in. So I’ve had to go nautical and rig up a cantilevered fence post with pulleys, eye bolts through the garage frame and a hand winch. Successful lift achieved.
