No , i don't think so because how can you control the 2 plates separately.The system comes with only one temp controller.The way it works in my
boat is as follows.My fridge is separated from my
freezer with an insulated panel that has a hole in the top and bottom to allow air to flow from the freezer into fridge compartment.The freezer has a horizontal
lift up door and the fridge a vertical side opening door.I set the dial at 2* and this keeps my freezer frozen and fridge cold.My freezer is 3 1/2 feet deep by 2 1/2 feet wide and 2 1/2 feet deep. Fridge is 3 1/2 feet high , 2 feet wide and 2 1/2 feet deep.
I can ship to Trinidad but you will have to pay for shipping
