I've just bought a 64 Overlander......lot's of work to do! Been agonizing over flooring choices and done a lot of looking around. Thank God for the net!
Armstrong.com makes linoleum (no asbestos) with lots of truly vintage colors and styles. Show ideas of how to use it. Most all of it comes in sheets (rolled). They only make to tile colors, a bright blue and a bright yellow.
Novalinoleum (Swiss company) makes some tiles with a few choices. And Forbo makes some great tiles and sheets. None of these have asbestos. You can see all of these including the Armstrong at iFloors.com.....they have the best color samples that you can copy and paste, or save as jpegs if you're set up for that.
I use Microsoft Image Composer, part of Front Page, to "glue" a bunch of tiles together to get a feel what a "field" of the stuff would look like. Even throw in some photos of fabric swatches, etc. to see how they look together.
Problem with linoleum is weight and installation if you're a do-it-yourselfer like I am. Not recommended for the uninitiated....that's me:>)
