Fixing up my truck?? ( People who know their stuff please )?

I know my stuff but have not a clue what you are asking. Really! "A system" Huh? What system? What in the Sam Hill are you talking about? Exhaust system? Sound system? Brake system? What what what? A truck is a complex set of systems. You can't get what you want 'till you know what you want. "Tent"? You going camping? Camper shell? What what what??? Sit down and write a question that can be understood. Take your time. You have all day!
