I needed extra workspace when I used my grill so I made cart from a couple of pallets. The design ideas are from several carts from this site and others.
I only had to purchase 2 wheels, 8 2 1/2" carriage bolts, and 2 plastic nail on feet so the cost was under $10 and used 2 pallets. Features stationary legs plus wheels and handle to move easily but be stable. Side shelf to hold pans.
