Not matching was my concern too, but it was free from a friend that replaced their flooring with tile. For free, it was close enough for me.
For what it's worth, other than to check on it, I haven't seen it again since I put the mattress in place.
There are a lot of decisions, we changed a ton throughout the build, used the generic benroy plans as a guide but modified a lot. I'm now in the process of looking for a better base trailer that will get a wider axle and new tires, trying to decide between buying or building.
