A neutral stone like travertine or even granite would be a lot less work. No matter where you camp, you will be in and out of the rig more than you think. Also, i'm sure you will have plenty of visitors at events. I wouldn't have black floors in my house.
Travertine is a soft high maintenance stone. Something in the color tone of travertine would look nice but not a good idea to use for a trailer.
