I think the question is less about what others have done and more about you and your camping style and flooring needs. Is carpet going to be a problem because of kids/dogs, wet environment? Is vinyl a better choice because it's easier to clean for you? Is the floor in good enough shape that laminate may work? If you're looking for something in between all that, epoxy paint
and runners would work well.
BTW: I camp alone with no pets and I can't wait to pull up the carpet and it WON'T be replaced with more carpet... YMMV
