Replacing rug with Laminate

[ChuckD37]

We had an accident on our last trip. A quart of olive oil was spilled on the living room rug. My Dear Bride says it is there to stay and perhaps it is time to replace the rug and linoleum in the kitchen and hall. The coach is 11 years old and we have enough improvements and upgrades that we are not going to replace it. In other words we like it... We are not full timers, just maybe 7 months a year in it. Sometimes more, sometime less, but about that.
The rug goes under the couch and dinette table and benches. (She would like the rug in the bedroom to stay.) There is a slide-out that goes over part of what we want to replace, about 18 inches The couch is a folding bed with storage drawers under it.
There are no marks on the rug or the linoleum that the slide is dragging on the floor so I hope the slide won't mark the floor. I do know it has to be thin. Now some of the questions....

First, is this something that should be left to tie Pro's or a DIY project?

Should there be a layer, felt or foam, under the laminate? and should it float or be glued down. I know wood has to expand but does laminate?

Do I have to take out the couch and dinette benches or can I work around them?

What type of laminate do you recommend?

How can I stop thinking about all this at night when I am trying to sleep? LOL

well now they have a stick down vinyl flooring that looks great its reasonable and easy to cut and work with ... might be worth looking into and it looks like wood

Go to youtube and look up loveyourrv. Ray, the guy who does those video's replaced his carpet with some sort of vinyl. It was also replaced on his slide as well as the stationary floor. He was very happy with the outcome. I think it was done about a year ago so he has had some time to find any flaws with the system. He lives in it full time with his wife and dog. He seems to have a lot of good common sense.

Take a sneak peak under the rug in some corner. Most campers I have seen all have wall to wall vynal layer down first. You might have something under there you like or can live with.
