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.
You don't have to be impaired to get a head nogging in our Jayco. Our trailer has a cabinet above the bed that does it regardless. I don't know what they were thinking when they designed the trailer but if you didn't want to bump our head getting out of bed you slept next to the sink.
