what to save from an old popup?

I just got an old Coleman popup, fiberglass & aluminum skin. Haven't seen much of the inside yet, but what I have seen looks to have been sheltered pretty well. What kinds of things might I salvage from this for my own build or for resale?
I'm guessing I can take a look at the stove, sink & fridge, plus any vents. There doesn't seem to be much metal for scrap recycling (drat!). The canvas is shot; it's all crumbly.
Mostly, I'm wondering where to be careful and where I can whack it for all it's worth ... I have some ideas, but expert advice is always better
Thanks!
