Post more photos if you get a chance. I'm going to do this exact thing in our motorhome. How hard was it to unbolt the driver and passenger seats? As for the choice of laminate flooring, I know some don't like it but I became a big fan of it after putting it in my house. I have a Golden Retriever and you hear his nails trying to dig into the floor when he's standing up and this stuff is bullet proof. He is unable to scratch the floor at all. It is much more tough than real wood flooring.
I have the same type of tile design as you do, but I'm thinking of leaving the tile in and putting the laminate around it.
