This is an amazing unit.  I used the youtube video to assemble the units.   Very easy to follow.  However, I decided not to install the side (table/tray).  All of the necessary tools come with the unit.   I purchased two.  I am going to get two more.  My neighbors absolutely love them.   It will use a lot of propane if kept on the highest setting.  The lower BTU units will not put off as much light or heat.
