Run to HD they are currently selling a fire box in the form of a small grill. If you are are afraid to get crafty I see no reason why it can't be used as a fire box. I think it's around $70. Good luck. Remember to always clean out the fire box after using it. That will make it last longer.
They slide in and out. -GHP

I use for added ventilation when needed
if you are allowed to BBQ then why would you not?
Yes, I did
The wheels are steel
1 big heavy box Consider the entire smoker fits inside the smoke cylinder (so that's the size of the box) I picked mine up (not home delivery)
It's either used or not the same product.
