Just make it blow out. On cool days don't turn it on and the fridge heat will stay in van via the vents behind sink/stove.

If you want a fan blowing in, mount one behind the grill that faces the top loading cubbies , the rear face of the sink/fridge. That will push the hot air from the fridge into the living area.
