The Roughneck(TM) gives you plenty of high-efficiency cooling power, but also has a lot of inner strength to handle rugged, off-road applications. Optional electric heat kit (#3904551) can be added to provide 5,600 BTUH of heat. 13.5" H x 26" W x 37" L. White. A COMPLETE UNIT CONSISTS OF AN UPPER UNIT & AN AIR DISTRIBUTION BOX (ADB) OR CEILING ASSEMBLY WHICH MUST BE PURCHASED SEPARATELY.
