Why RV with CrossFlex PVC roof has popcorn-like ceiling?

[brightsky]

RV usually has a TPO, rubber or fiberglass roof, and it has a smooth ceiling. But Coachmen Freelander has a CrossFlex PVC roof, and it has a popcorn-like ceiling (not smooth).

Not sure what material is used for the ceiling. Will the popcorn-like ceiling start to peel and the material will fall down from ceiling? more off-gassing?

I post here since Coachmen forum is very quiet and Jayco Forum is very active and friendly

To be honest with you, I don't think that I have seen that material in person. It almost has a rough coat plaster type appearance.

I don't know if it would be any more or less likely to peal or crack than a smooth textured finish. However, I would like to know if anyone else has experience with something of that design.

From what I can tell it is a 4x8 ceiling panel and I imagine it has the same type vinyl wrap that the rest of them have but this new style is just textured.
