I think you have a good idea. Do various Google searches regarding keywords related to the trucking, the trucking industry and the lifestyle. That will help you identify competition and give you some ideas to pull from.

You are correct, the trucking industry is not exclusive to men. There are more women getting into the driving profession. "Lot lizards" excluded. My fiance used to drive with her husband years ago. I used to date a girl who's father drove long haul and it was not uncommon for her mother to go with him on a long weekend trip.

Listen to people that are successful and have fun with it!
