I have a floor that holds up my ammo cans in the front bay. At night I take that floor and put it across my captain boxes. My second bay is my cooler, third bay captain boxes and 4th is my large dry box. I sleep on 2nd, 3rd and 4th bay long ways. My flip seat gives me support for my feet. This way I don't lose my pillow and still have plenty of space to put junk around. Also my bimini protects me from the rain at night that way.
