had a friend with a Winn and his slide topper tube flexed so much that it rode up over the top of the slide bending the arms. Had to come up with new arms etc. and Camping world fixed it don't know what they did to fix it.
We did a temp fix on his by rotating the awning tube arms further away from the slide so when it was going out and flexed it didn't ride up over the slide out.
Check the awning manual or check you tube and you can retention the springs in the tube.
Can't recall where I saw it but remember reading that you could buy a tube that fit inside the roller tube to keep it from flexing.
