Received my Blackstone 28" Griddle w/ Hood & Accessory Rail System. The instruction manual was pretty straightforward. However, the shelf hole that is supposed to line up with the hole in the legs. 1 was slightly off, and I had to do some fancy maneuvering to get the thumb screw to get a bite. Other than that, easy install with 1 person. 2 would be ideal (for lining up the griddle post pegs into the frame).
