I would have to say a definite yes, or rather a MUST, on the Kingsford charcoal.
Being a B camper I know the value of space, that's why I would recommend something like
this. Granted it is expensive and I didn't pay that. You can find this type on the web for all sorts of prices. I had a friend in the HVAC business cut 4 pieces of sheet metal to my specs with air hole in the bottom, bought a 4' piano hinge. Cut it to 12" lengths and pop-riveted it together. Cut an old BBQ grate to fit inside, with stops. Then made a folding handle. A lot of work but fun. Just to see if I could do it. Turned out great.
My other suggestion would be
this grill. We bought the complete package with the propane adapter and love. We like to dutch oven cook so it is great. A really nice grill and with the propane attachment and 12"cast iron skillet is an excellent (fish) fryer.
