I moved into a new house last September, and the driveway at this house is sloped. The driveway is where I would like to put the grill, but I am unsure of how to level it. Any ideas? I was thinking possibly a rubber wedge of some sort under the leg. I have a composite deck on the back of the house, and this was where I was originally going to put it, but have since changed my mind due to safety reasons. So, the driveway it is. Any help is much appreciated.
