My Rockwood popup has 4 latches, one at each corner, that fasten the top to the body. You pull down on the latches to release them. After they're unlatched, I just insert the handle in the winch and start cranking to raise the top. Hope yours is similar.
My 06 Fleetwood Niagara pop up camper has four latches holding the roof to the body of the camper during travel. Once on site and leveled side to side, I simply unlatch, grab the crank and crank 'er up 51 or so turns.
