I'm not sure how it will hold up under equipment. I know quite a few folks who bought it and said it was fine to drive on, but if they tried to use a jack or a tool chest on it, it tore.
If you check, there are different thicknesses available. The one you see at Sam's is the thinnest. If you buy the heavier grade ones, it ends up being pretty pricey. I ended up putting rubber tile from GregSmithEquipment.com.
I'll put the link to the different roll out floors.
