Going to be a Black Crown night... So do you sleep head or feet towards the front? If your sideways, well, you're either short or someone built your camper wrong. Survey not for you.
Head to the front for me. I'm 6'3" and like to keep my pillow trapped on the bed and room for my feet to overhang the end of the bed if needed. Getting down from the cabover head first would be a challenge for my old body :-)
