I was thinking of doing that or taking it out and putting XPS in the ceiling
I like the metal roofs. I wasn't going to take mine down when I bought a bus. But the bus I bought had perforated ceiling that I didn't like. And speakers in each panel. So I took mine down and decided to insulate with XPS.
I guess the XPS will be better insulation. Plenty of people leave theirs in and don't mind. More people take everything out and run spray foam. My bus is 2003 and the fiberglass was in good shape when I took it out. The walls were nasty though. I imagine yours isn't too bad unless you have a leak or something. But are you going to be in hot or cold temps? Leaving all your windows in place? Raising the roof?
All those answers will lead to a better decision that works for you.
