Garage door opener as a lift for a camper shell

I have an old garage door opener that I was thinking of using as a lift for a camper shell. I'd attach it to a block and tackle to amplify the pulling force. The problem is I have no idea how much force a garage door opener typically has. I know the spring carries most of the weight of the door but I was hoping the opener itself would be good for at least 100lbs. Has anyone ever done this?

Thanks for any advice,
Rich
