I've never had any luck hauling fish in a galvanized tank. Adding salt and electrolyte makes the inside walls of the tank the same as a corrosive battery. I'm with esshup here, if it was that easy we'd all be rich. I have just over 11k in my new 400 gallon rig and every piece installed is to maximize getting fish from point A to B as stress-free as possible. It's not just a matter of putting water in a tank.
