Designed and built a custom truck bed sleeping platform and interior system to maximize usable space, comfort, and functionality within a pickup bed camper shell. The project began with manual measurement and CAD modeling of the vehicle interior to ensure accurate fit and clearance. The platform was fabricated from flat-panel plywood components designed for efficient material use and straightforward assembly. Custom cushions were pattern-designed, fabricated, and upholstered to fit the platform geometry, creating a durable and comfortable sleeping surface. The final build balances modularity, weight, and practicality for extended outdoor use.
