What is this? (Picture inside)

[yxan]

I was looking at a 2001 Bigfoot 21ft

And came across this inside all the corners and behind cabinets

What could this be? It's the black seeping through the white headliner

to me it looks like mold/mildew.

The seller steam cleaned area above door, you can clearly see where he left off.

It looks like a line of adhesive showing thru. Not dangerous but of course less than attractive. Adhesive bleed thru is not too uncommon on headliner types of materials. Some adhesive formulas are more prone to it than others.

Weep holes in the windows plugged?

with weep holes you are thinking it leaked or condensation?

this was inside pretty much all the cupboards front and over kitchen (model is a 25B21R

so anywhere in opened cabinets over dinette, and kitchen sink id see it. It is very straight in shape, so doesn't look like classical mold as mold would probably be in a more random pattern.
