Its a pretty easy fix, you have to remove the ends of the bungee cords where they attach to the rear roof. Its best to back near the front of a garage a few feet out and separate the roof panels and rest the rear roof against the house, then tension will be off the springs. Here is a link, one of many on youtube on how to do this repair, its on an Aliner which is similar. For the skylight leaks use Eternabond 3 inch tape, this will seal the edge and no more leaks.
