Been sick with a stomach flu for the past week bus should be able to get back to the bus Monday
I'd take it out. I have seen worse pictures than the one you posted, but it's old, looks like it might have traces of mold, and it will not insulate nearly as well as the same space filled with closed-cell foam (either board, or sprayed).
The only reasons to leave it in are to save a few hours of work and a couple of hundred dollars. Those reasons might be necessary for some, but I wouldn't find them compelling ... but it's your bus
