I want to build a ladder base for some cabinets/drawers under a basement stairway. As discussed here before, this is for leveling and separation from possible moisture in basement. I've not built a ladder base before. I'm assuming the 'rungs', for and aft pieces of the base are to match location of the cabinet partitions? I can then attach cabinets to base with pocket holes in the partitions. How's all this sound?
