Finally installed some "wood" flooring in my Rv. I've always wanted to do this to an Rv, and it was surprisingly easy. No more heinous beige carpet everywhere, and infinitely easier to clean.
I used Allure flooring from Home Depot. It took 2.5 boxes at $50 each to do my whole 24' Class C. Took about 6 hours including tearing out the carpet.
Anyway, if you're considering doing this, go for it. Just go slow and start with the easy (straight) areas.
