I replaced my awning fabric last weekend. Was actually very easy. A couple of guys at the campground came over to help support the tube while I slide the fabric in the channel on the MH.
I also have to replace the spring torsion assembly on the lock side. 2 rivets hold it on the tube. Is that what gave on yours? Or did the tube itself tear?
I watched a couple YouTube videos before hand, and kind of did it my way during, just because some of the ways they did it on YouTube seemed not as simple.
Its really fairly simple, especially if you are comfortable on a ladder or the roof. But a couple of extra hands will help for sure.
Took about 45 mins, with a beer break.
