If the batteries were dead on the TC, then it's probably the power circuit on the truck. You should be able to look up what fuse it will be on the truck.
I like battery tenders if you take the batteries out. If it is fairly close, I'd just plug in.
Could contribute to dead batteries, but not the sole cause. The truck isn't going to fully charge a pair of deep cycle batteries off the 12V lead unless maybe you drove from here to New York and back without using the camper batteries.
OP, Why not test that pin on the trailer plug first to verify power or not.
