Check out this really cool log hauler. It's a steam powered crawler. An engineer sat in the back and stoked the fire while one guy basically rode on the front axle and steered. Apparently the steerman had issues with cinders going down the back of his neck and used to wear thick leather suits to keep from getting burned. This steamer has a shed built on over the front axle to stop that from happening.
