This would be my first step. I replaced the topper on our mh a couple of years ago and if i remember right, it's spring loaded but still fairly easy to turn by hand.
Open the slide, climb up on a ladder, and try turning the awning roller. If you're at the front, rotate it counterclockwise to see if the awning fabric loosens and droops. If it does without too much effort, then there's something else going on.
