At a dollar each, I doubled up on these in our Escape
, overlapping them so that three screws hold two pieces of hardware. I don't know that I needed to double up on all of them, but after seeing pictures of various RVs where the cabinets and drawers emptied onto the floors it lets me feel relaxed while towing.
We also fitted two of the cabinets with a 1x2 board across the bottom of the opening to keep heavy items from sliding around and pressing against the doors. This includes the cabinet under the sink where there is a cardboard box with our pots & pans. The other 1x2 is in the pantry cabinet where we have a box to carry canned goods and dry goods.
