I keep the truck system (24 volt) totally separate. (best kept original)
From the truck batteries I run a sterling battery to battery charger, 4 step, 24 to 24 volt, to 2 x 12 volt =24 volt house batteries, direct from these I run the fridge freezer at 24 volt,
I then run everything else, "house wise" through the 24 to 12 volt dropper, including the bed, but I have an emergency supply from one of the house batteries that I can patch in to the output terminals of the dropper, if it fails.
