Universal Large Bunk Slider Van Window – VWD BUNK4015L SE Series Driver Side
Many van conversions struggle with the comfort of the sleeping area. Full-size windows compromise privacy and structural integrity, while small vents do not move enough air. A properly sized bunk slider window solves both problems.
The VWD BUNK4015L SE Series Half-Slider is a universal, large-bunk window designed to deliver effective ventilation, usable natural light, and exterior stealth styling. It installs into flat wall panels of vans, RVs, trailers, and overland builds using the included template.
Designed For Sleeping Comfort
- Moves hot air out of upper sleeping areas
- Creates nighttime cross-flow ventilation
- Provides natural light without a full wall opening
- Maintains privacy while parked
Unlike roof vents alone, side airflow removes trapped heat where people actually sleep.
Half-Slider Ventilation System
- Adjustable sliding glass opening
- Spring-loaded slam latch secures the window during driving
- Integrated insect screen
- Ventilation control instead of permanent opening
You control airflow based on weather and temperature.
Solar Privacy Glass
- 17% tint reduces glare and heat

- Maintains stealth exterior appearance

The van appears empty outside while remaining bright inside.
