It has a very tough polyurethane coating on it, and is as tough as any wood floor. To some degree it can handle pressure loads better, as it bounces back better than wood, which will leave a dent. However, if the point load is extreme (like when I am wearing my high heels

), it can get crushed and not bounce back. Slicing will cut at it easier too.
All that said, I would not hesitate to use it in a trailer, and in fact am considering doing this myself. If it is maintained, and spills cleaned up fairly quickly, it should perform great. Do make certain you are using a good brand, as the cost for that small of a square footage would be fairly low.
BTW, with my company, we have installed quite a few thousand square feet over the years, with no callback issues at all.
