Mobile Home Equipment & Parts Manufacturers, Licensed and Bonded. In the early 1930's when West Texas was truly considered one of the last frontiers, an immigrant from Denmark "my Grandfather" came west seeking his fortune, his name was John "Jack" Olsen. Using the skills of his hands and mind he manufactured parts to repair equipment in the oil fields and followed the rigs around this part of Texas. Out of necessity the idea was born to make a house on wheels. First an "RV" on a truck chassis, then later a trailer house made out of tank steel pulled behind a converted Cadillac car.... About this time a man from Arkansas came west with his family to find work and apply his skills as a "mule skinner", his name was L.A. Johnson "my Grandfather". He found work with his teams of mules moving oil rigs in the west Texas oil fields. His son V. W. Johnson "my father" became a house mover in west Texas for some 30 years. In 1968, his son, Dan Johnson, began applying the skills he had learned moving houses, to moving mobile homes. In 1980 he went on to open Big J Mobile Home Sales which today employs both of his sons Todd Johnson and Rodney Johnson....
