Looks like a pretty small rotisserie. I'd suspect one would have a hard time with the height and sometimes width on larger cuts of meat like whole brisket. Aluminum pans may also not fit. 8" seems okay for most cooks, but the clearance with the above rack might be tight. As far as a chicken or rib cooker goes, this would probably be pretty nice.
Works similar to my Kingfisher Commerical. Rotisseries are a wonderful invention. Since this cooker is offset to the rear, you won't have any hot/cool spots to reposition meat as needed. Mine is offset to the side, so I can move meat up and down the rack either closer or further away from the fire. Don't know if this is an advantage or disadvantage. With the rear offset, everything gets about the same heat. However, you can't move smaller cuts further from the fire to get everything done at the same time.
