Trying to overcome a dead battery, especially multiple dead batteries, can sometimes yield odd results. It drives me nuts watching these "revival" videos on youtube where the host takes one of those wimpy little jump packs, clamps it on to a stone dead battery, and then spending the next 30 minutes scratching their heads as to why the car won't turn over.
Occasionally you can get away with that, but most times you really need to take the dead batteries out of the equation so they're not pulling the entire system down.
It is entirely possible that your truck's charging system was working fine, but it is not designed to jump start a dead battery. The charge line is 10ga at best.
Jumping the battery worked because jumper cables are much heavier and could pass a lot more current.
