  "1. Any self-propelled or non- self-propelled vehicle, with a length exceeding thirty -five feet (35’), so designed, constructed, reconstructed or added to by means of accessories in such manner as will permit the use thereof for human habitation, and so constructed to permit its being used as a conveyance upon public streets or highways"
