In the interest of time and effort, try adjusting them, wheels on. If they don't adjust out enough to lock up the wheel, then it's time to pull the drums and take them to FLAPS to be measured for ID. Could be why you never had good brakes to start with, some dip wit did a brake job and took the drums beyond limit, so even though they "look fresh" they should, since the shoes weren't rubbing on them, ha.
That truck should be able to lock up the wheels when you stomp the brake, so something is not where it should be.
