In answer to your question about the AGM batteries being charged by the truck:
No problem if you have a heavy-duty alternator. That's what my Tiger has (Chevy 2500 HD) and it charges two Lifeline 6V AGMs in the camper part of the rig just fine whenever the truck engine runs. Thick wires. Shortest run possible.
Does your plan call for some sort of battery isolator to keep the extra battery bank from draining the truck battery? It should.
I cannot answer your inverter or TC questions. Sorry.
I have dual 125amp alternators and I do plan on an isolation relay.
