Do you really need 60 amps of charging for your camper batteries while driving? Is the DC-DC charger going to be your primary means of charging them? Or will you be using the DC charger to keep from running your camper batteries down while driving?
I run my fridge in AC mode from an inverter while driving, and that’s about a 28 amp intermittent load. I’m using a 40 amp Redarc DC charger to keep the camper battery charged up. If we dry camp for a night or two and run the camper battery down, the DC charger might need to go to full output for a while when we start driving again. The input to the charger is fused at 60 amps, so it will never exceed that. With the size of the wires I installed to feed the charger, I doubt it will exceed 50 amps. I haven’t monitored the amperage output from the charger while driving yet, but I have forced it to supply its full 40 amps while idling, and it will do it.
Consider carefully what you need the DC charger to do for you, and size it from that. Mine isn’t my primary means of recharging the camper battery. If we’re needing to use a lot of power while dry camping, I will get my Yamaha 1000 generator out and let it provide that power and charge the camper battery as well.
