Here's my thoughts. Get yourself a good charcoal grill and problems solved. I built me a collapsable charcoal grill over 20 years ago and am still using it today. It was so popular I use to sell them to motorcyclists at our IBMC campouts because it folded down into a cake pan for storage. It doesn't burn the top of the picnic table either and in a pinch it can double as a small firepit. We've had as many a 6 guys sitting around it on a cold night. It will char your food if you don't watch it but hey, the food doesn't cook itself, you do!
