Up front there's a queen bed with overhead and under-mattress storage. There's great airflow and natural light thanks to large windows at each end of the bed. An optional Fantastic Fan is mounted in the ceiling above the bed to further enhance airflow if needed. Under the bed is the rig's electric water pump and somewhat smallish 30-gallon fresh water tank. There are bright reading lights on each side of the bed as well as on the ceiling. Speaking of lights, the D291 has no less than 12 interior light fixtures, and many feature multiple bulbs. At night it's possible to drench the interior with good strong light.
