Overhaul on the engine has only 30,000 miles on it. Engine is a Cummins 350 small block. Sleeper included. No A/C but a retro unit could be installed.The Road Commander 2 has a bolted frame made of high tensile steel, while the all-aluminum cabin is hydraulically tilted. This allows access to a wide range of available diesel engines from Cummins, Caterpillar, and other manufacturers. The available range in 1977 was from 190 to 450 hp (142 to 336 kW). An unusual feature for the time was the RC2's pull-out drawer containing all electrical fuses and connections, located inside the cab. Serious buyers only! No trade, or payments.
