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. Some trucks need a relay to allow charging while driving. If it used to work, then it isn't that.
I like battery tenders if you take the batteries out. If it is fairly close, I'd just plug in.
