Increasing charge rate from TV to TC?
It is my understanding that the amount of charge going to the truck camper battery is determined by how much the alternator needs to send to the truck battery. So if the truck battery is nearly full ...

Probably a problem with the wire size from alternator to the TC batteries. I would recommend installing a #8 or larger wire from the alternator to the relay, then a 50 amp automatic reset circuit breaker, then to the connection at the camper. This also needs to be rated at 50 amps, then to the TC battery.
The alternator voltage should be about 0.5 volts higher than at the battery while charging. Once the battery is almost full, then the alternator senses the battery voltage, and drops it's output voltage to about 13.6 volts to avoid boiling out to much water from the truck engine batteries.
A relay like Grainger part #6C017 will carry all the amperage that you need, and has silver allow contacts, for almost 0 voltage drop across it.
