My 19 yo son put this grill together for me and it took him about 4 hours but he was watching a basketball game while he did it so I'm sure it could have been done in significantly less time.  It is my dream grill!  I no longer burn food because the tray that holds the coals can be lowered to  level deep enough to allow slow cooking and the grill plates are non stick and i am able to pull all of my meat off the grill without leaving some behind.  It is large but was not expensive compared to other grills in its class.  I picked a winner this time!
