I agree with Nick. Wire brush and Rustoleum are the ticket. The instructions say to use a wire brush to remove loose scale -- tailor made for your situation with that bumper. For the cracking bedliner stuff I think I would get as much off as I could when it was cold so it could stay stiff and you can snap off big chunks, maybe use a putty knife carefully. And then I would move to a heat gun and a small putty knife after that. Probably lacquer thinner for any remaining residue -- rubber gloves, eyewear, etc.

And that camper is cool.
