My 75 has one from the firewall to the passenger valve cover bolt and the primary battery cable runs to the alt bracket. Apparently fine for a new truck. But unless you are doing a frame off restore, best to assume that corrosion exists in a lot of the body to body bolt connections and add a few more grounds.
IIRC, headlights ground to the core support so a ground from battery to there
Taillights ground to the bed so as mentioned already, bed to frame.
They are a PITA to replace but check the grounds from fuel tank sender(s) to frame.
If your battery cable runs to an engine bracket, I would run a heavy ground from engine to frame.
There is a ground bus high up under the driver's side dash that often sports corrosion. Another PITA thing to get to.
