So I'm debating leaving a space for the cooler inside the trailer in the pull out slide. Few thoughts here, I'll use the cooler in other places, I'll need to fill it often, and I'm taking up space for a possible pull out sink on the drivers side. My thought now is to ditch that and keep the cooler in the back of the truck. However if I don't build a space now a future fridge won't work. Decisions? Any thoughts?
