The method 2200 can further include aligning a burner box with the grill cart in the upright state, step 2204. The method 2200 can further include coupling the burner box to the grill cart, step 2206.

FIG.23 shows a flow chart depicting a method 2300 in accordance with various embodiments herein. In some embodiments, the method 2300 can include uncoupling a burner box from a grill cart in a folded state, step 2302. The method 2300 can include separating the burner box from the grill cart, step 2304. In various embodiments, the method 2300 can further include transitioning the grill cart from a folded state to an upright state, step 2306.

In some embodiments, transitioning the grill cart from a folded state to an upright state can include rotating a front frame from a folded state to an upright state, step 2308.

Transitioning the grill cart from a folded state to an upright state can further include rotating a first side frame and a second side frame from a folded state to an upright state, step 2310. Transitioning the grill cart from a folded state to an upright state can also include rotating a back frame from a folded state to an upright state, step 2312. In some embodiments, transitioning the grill cart from a folded state to an upright state include first rotating the front frame, then the two side frames, and finally the back frame. In other embodiments, the back frame can be rotated first, followed by rotating the two side frames, and finally the front frame. In other embodiments, one side frame can be rotated first, followed by the front and back frames, and finally the second side frame. It should be understood that other orders in which the frames are rotated are possible and included herein.

The method 2300 can include rotating the grill cart 180 degrees relative to the burner box, step 2314. Rotating the grill cart 180 degrees relative to the burner box can involve rotating the grill cart, the burner box, or both. Rotating the grill cart 180 degrees relative to the burner box can take place after the burner box is separated from the grill cart and before the burner box is recoupled to the grill cart, such as step 2314 taking place before step 2306.

The method 2300 can further include aligning the burner box with the grill cart in the upright state, step 2316. The method 2300 can include coupling the burner box to the grill cart in the upright state 2318.
