The pig roaster is a trailer within itself. It can be towed with either 1 7/8" or 2" balls. It comes with two full 40lb tanks of propane. This is a great way to attract the crowd for your party. The Pig Roaster can be used for more than just pigs. The mesh grate makes it possible to grill hot dogs, hamburgers or steaks for large parties. The Pig Roaster also has a deposit to insure it comes back clean.
