"Newer" Ford trucks don't charge house batt's?

I would check the wire gauge on the factory charge wire, the one on the chev is too small to do much. I ran a new 1/0 100 amp charge wire from under the hood and am using DC to DC chargers with four Trojan T-105s. The Redarc DC to DC chargers work great, I am going to run two of their 50 amp units in parallel, they also incorporate a MPPT solar controller that the unit will give priority to if there is solar power being generated.
