If you want to roast a whole hog, lamb, or goat, you can fit small animals onto some horizontal smokers. Or you can buy rigs specially designed for the job. They range from simple spits that you turn by hand crank or motor and the animal rotates above or to the side of a campfire. One popular design, jokingly called the Cajun microwave, is a stainless steel lined box. You close the lid and put the coals on top. The meat roasts rapidly in this indirect heat, smokeless coffin.
