Our 2001 Safari 25 had something that looked like formica on the wall behind the galley. It was NOT formica. It was a vinyl layer glued to some kind of a fiberglass-like substrate. The previous owner had hot-glued a picture to the wall and the weight of the picture ultimately pulled the vinyl away from the substrate. I ended up having to cover it with something so we used the stainless mosaic tile from Lowes. It makes a nice look behind the cooktop.
Just a warning - make sure it is formica before sticking anything, particularly anything heavy, to it.
