Similar story with our 2006 AF 990. After purchase, on the return trip from Texas to Ca. The wind buffeting the front brought out all delamination bubbles on the nose and over cab sagging, looked like yours.
After head shaking estimates I called AF in Oregon, made an appt and had the whole nose, top to bottom from top seam to bottom of sliding window and underneath bed replaced. Wood, filon and everything for 2k, granted it was about 5 or 6 years ago but they treated us great and threw in some extras. We made a vacation out of it. Took them 2 days and looks brand new.
A friend had the sagging delamination over the cab, under the bedroom, he drilled a few holes injected glue pressed up with wood and
it turned out fine.
Hope this helps
