The instruction manual included in the box is awful. Pictures are very vague and don't match the model you are putting together. 2 person, 3 hour job. There is no meaning whatsoever to "Reddi-Built".
But! Great heat with 3 burners on the Monarch 320; easy to change up the temps on different side. Great space for a "smaller" BBQ to make an entire meal for 4 people.
Bit more expensive but quality matters - had the last BroilKing for almost 8 years.
