I don't like causing a slow death to my alternators diodes which increases the AC voltage ripple thru the dc system. Which in turn can slowly destroy the ECM, PCM and other electronic circuitry. It can play havoc with sensors as well. Smaller wires to the batts from the truck will help slow the amperage demands that sometimes are too much for the trucks alternator and cause damage to the diodes.
Best to charge slow off the truck (not big wires) or use Solar collector and/ or a small Quiet Generator. My camper walls are thin and you can hardly hear the honda 1000 watt gen even when raining and underneath the camper its quiet.
I suggest that all truck/ car owners check for AC ripple occasionally to keep dc system healthy. Esp. after installing a rebuilt alternator. Even new has been tested with too high of AC noise in the system.
I learned this test from U tube..... testing for AC ripple.
