My husband purchased this to place our portable Weber gas grill on.  We bought two large tiles 20"x20", at our local building supply store, to place on top of the storage box. The tiles deflect any heat from the grill and allow for a very easy clean-up.  The storage box hides the propane tank, and a simple modification, to the back of the storage box, allows the propane tank hose to feed out to the grill.  A perfect solution and much more attractive than the standard grill cart. The actual color of the storage box is much more darker than the picture shown.
