Delivery was horrible. This was thrown off the back of a pickup truck in my driveway. I guess this is what they mean by ground delivery. I dragged the extremely heavy box to the front porch until my husband got home. That night we opened it and make sure every piece/part was there. Completely surprised that it was all there with only a little dent to a side panel that won't be seen. We have not installed this yet but we are hoping it meets our needs.
