Dometic slideout topper tension adjustment

[studebrucer]

my widest slide has slack in the topper, very annoying when windy. I have a Newmar Ventana with Dometic slide toppers. I want to adjust the tension to take out the slack. I have seen many videos on replacing the fabric, but none of them are adjusting the tension. Would love some guidance.

Have you asked Dometic for a manual on how to increase spring tension? What about Newgle?
