Someone suggested this to a friend after he was saying their gas grill wouldn't stay at 250F while slowing smoking their food. It was mentioned this would increase the distance from the fire, possibly reducing the temperature that would be at the far side of the cart (the very top here). But, they mentioned they were trying to smoke it. Next time, I'll refer them to the "Good Eats" show on smoking. You put the fire somewhere separate from where the smoking happens.
