Trailer home needs ceiling repair.

I just got a call today from a new customer about a sagging ceiling. I looked at the job and this is what I’ve determined.

The ceilings are made of fiber tiles. It’s a brown fiber pressed together almost like a low grade of MDF. They have a layer of white paint on the inside(room side). There were a couple tiles missing and I can see the roof. I guess the roof used to leak before they repaired it and this is the cause of the sagging. Looking ito the ceiling I noticed there are no beams or rafters but a bunch of 2×3’s forming a triangle to make the shape of the roof.

My question is: Is that strong enough for me to apply 3/8” drywall? Or would it make more sense for me to try to lift the ceiling back up and piece together the missing tiles?. Or should I convince them that I need to replace the whole thing. I am concerned with the integrity of those 2×3’s. They dont look to strong. I never worked in a trailer ceiling before and want some guidance from an experienced homeowner or contractor. I hear these fiber tiles can be a can of worms if I try to repair them.

Any help would be much appreciated
