The Renogy ignition trigger lead and/or commonly used battery isolator accomplishes would you're describing. If the Renogy ignition trigger lead detects a "nominal" 12vdc, the charger turns on. If the 12vdc goes away, it turns the charger off. A battery isolator operates in a similar fashion, but it's much more voltage selective.
If you are towing or using a truck camper, the B+ wire on the 7 pin trailer harness is almost always wired to a KEY-ON circuit. Now additional wiring required.

What pianotuna is describing is a 3-4a drop in output charge current at idle (vs. driving).
I mis-understood! I would be unhappy as well. I don't think that is in the spec sheet !
