How much battery charging from alternator?

My older truck had a factory installed (camper package) isolation relay and #10 charge wire back to the 7 pin trailer connector. I had istalled an analog amp gauge in the circuit. The most I ever saw with a nearly dead trailer battery was 15 amp.
My newer vehicle has no isolation relay, power there all the time. I think I like that better as I can rob power from either battery if one is dead, (truck or trailer). Also when camping with hook ups converter keeps trailer battery and truck battery topped up. If you don't want that simply unplug.
