One option that may "transition you" into an adequate battery configuration would be to move your current battery pair to the refrigerator only circuit and turn the refrigerator off when possible (don't run the ice maker at all when on batteries) and buy two GC2 or EGC2 (higher amp rating) to operate the trailer systems. That way you'd have increased capacity for the furnace and continue to have availability from your old batteries without discarding them.
Once those 12 volt batteries finally die, replace them with the same type golf cart batteries by shifting the existing ones to the refrigerator circuit and installing the new ones on the main system.
