In my grilling area, I ordered 3 stainless steel food service carts with locking wheels from Amazon. You can order as many as you think you need and configure them in an arrangement that works for you and your space. They're inexpensive, portable, and easy to clean. I'll add links of what I purchased.

I have a 270 GS smoker/grill sitting on the shorter table. I use the two taller tables for prep, cooked food staging, etc.
I also ordered 2, 32 gallon trash cans on wheels from Lowe's where I keep charcoal, charcoal chimney, wood chunks, bbq tools, a small stainless steel shop vac, lighters, etc.
Additionally, I have a Step-On trash can from Lowe's that I keep a liner in to dump ashes, used aluminum foil, and anything else I don't want to throw away in the house.
Good luck! Hope this gives you a few more ideas to ponder for your grilling playground!
