Thanks for all of your replies. I now feel even dumber than before and that was quite a hurdle.
Some of these comments are just way over my comprehension level, so I don't know if my question has been answered, or not.
I should probably restate my original query. As I am now configured, I take power from the combined battery output tap and send it to a solenoid and on to the camper through a 10ga. stranded wire. It seems to me that the voltage regulator is limiting the output to the camper batteries when I am driving because it senses that the truck batteries are fully charged. I have a Trimetric battery monitor installed and output to the camper batteries with the truck running is only in the 5-8 amp range. It seems like I should be able to get more out of the alternators than that.
In simple English, is there a way around this without having to rewire everything? In my owners manual, it briefly references an option for what it calls an alternate battery and shows an image of a connection that is supposed to be located on the firewall near the rear battery in the truck engine compartment. I have briefly looked for that connector and can't find it.
