Remodeling my 1978 Ticonderoga!!

So me and my step father decided to completely remodel my little pop up camper I’ve had. Started with ripping out the floor and trying to make alittle bit more room. Little did we know the roof has been taking in water. So the roof is gonna need a complete make over! Canvas all around is in decent shape. But I would like to replace a few parts of it due to deteriorating on some parts. Also one side of the lifting cables is snapped. Was snapped when I bought the camper. I’m trying to figure out how to fix the cable system but alittle confused. Any suggestions would help my friends. Thanks!
