DC to DC charger
Thinking of installing a Victron charger for those days on the road when solar is not available. Can the charger be used in conjunction with an inverter (2000 watts) to run the refrigerator on electri...

I just use a pair of 8 gauge wires from the truck battery to the camper batteries. That eliminates the voltage drop of the 7 pin and puts a nice charge into the camper batteries whenever I drive. I use a 200 amp blade switch that is mounted on the truck battery to isolate the truck battery when the situation calls for it, but that is rare.
The reason it’s working for you , and also for me , is the age of the truck . Newer trucks , last decade , have smart charging , meaning as soon as the starting batteries are satisfied charging goes way down , so the house batteries would get very little , especially with the voltage drop.
That is not true on newer GM HD trucks, my 2019 Chevy 2500HD sits above 14 volts, when changing my batteries it will ramp up to just above 15 volts @ 50amps.
According to the above statement I should have a smart alternator, but I have yet to see this mysterious lowering of voltage a few people on here keep stating. So maybe Ford and Ram do but my 2013 and 2019 Chevys don’t or if they do the alternator is smart enough to ramp up under heavy load.
