The point of the DC-DC converter (charger) is such that you can ignore the voltage gyrations of the alternator and any voltage drop in the wire and get proper charging voltage on the trailer battery. You no longer care what the vehicle is doing or how it works.
DING DING DING ! We have a winner !Add in, most DC-DC battery chargers also do a "proper" 3 stage charge on the house battery.

Or put another way, even though the trailer battery is needing a strong charge, the alternator is only putting out enough to float charge?
Basically, yes.The house battery would charge but at that rate it might take more than 24 hours.
