nuCamp Cirrus 920

Goal

Define the aluminium body system that interfaces the OpenOverland sub-frame with the nuCamp Cirrus 920 truck camper.

Architecture

The body has two functional zones.

Lower zone — wheel well enclosures: The lower boxes wrap around the tire positions and form the wheel wells. No separate wheel well structure is needed. The departure angle geometry is integrated into the rear lower faces.

Upper zone — storage and camper platform: The upper section provides the full-width deck the camper sits on, the structural top rail for the tie-down receivers, and the upper storage compartments accessible from both sides.

Tie-Down System

The camper is secured by four stainless turnbuckle rods — one at each Torklift bracket position.

• Right hand thread one end, left hand thread other end — cannot unscrew under vibration
• Forged stainless jaw ends
• Receiver points welded into the structural top rail
• Load path: camper bracket → turnbuckle → sub-frame

Storage

Lower boxes:

• Form the wheel well enclosures
• Departure angle cut on rear face
• Tail lights recessed into the departure angle faces
• Mud flap bracket integrated into bottom rear edge

Upper compartments:
