Wallpaper vs RV

I think I might be going in another direction, I'm thinking of using that grey carpet felt they use on speaker boxes, if you look at my first picture, the camera flash makes the wood stain look a bit blue but in person it's more grey than blue, and it would fit in pretty good with the light grey Formica and the black rubber flooring. But that all depends on how hard it is to install. I'm guessing 3M super 77?
