VWD Universal Overlander Bunk Window 36-3/4" x 13-1/8" O.D. (OVR3511) is a flat half-slider bunk window with solar privacy glass and a black aluminum frame. It adds light and airflow to the bunk or rear cargo area of a camper van and can be installed on either side of the vehicle.

This window only installs on flat walls or low curve radius vehicles such as the 2007+ Mercedes Sprinter, 2014+ Ram ProMaster, and 2015+ Ford Transit. It will not work with older Chevy and Ford models that have deeper curve side window panels.

Who is this product best for?

Do Campervan HQ van windows come with instructions?

Most van windows are sold for DIY van builders and may not include manufacturer instructions because many manufacturers assume installation by someone familiar with van window installation. Check the Campervan HQ van window installation blog for guidance. For CR Laurence van windows, you can also search YouTube for CR Laurence window install videos.

Do van windows require adhesive and primer?

This is a clamp-in van window. Clamp-in windows do not require primer or urethane adhesive because they seal against the van body with weatherstripping, an exterior compression ring, foam gasket tape where specified, or an interior trim ring. You still need an existing opening, so cargo vans without windows require the correct cutout before installation.

Do Campervan HQ van windows ship for free?

Most van windows do not ship free because large windows often require truck freight or special handling. When available, warehouse pickup can reduce or refund shipping costs. For large multi-item orders, contact Campervan HQ for an individual quote.

What should I check when a van window is delivered?

Inspect the window shipment before the delivery driver leaves. If there is damage, have the driver note it on the Bill of Lading and provide a signed copy. Without signed damage notation at delivery, Campervan HQ may not be able to make a shipping damage claim.

What is the return process for damaged or defective van windows?

For delivery damage, Campervan HQ needs a signed Bill of Lading showing the damage and photos of the damage. For a defective van window, Campervan HQ needs photos of the defect and will request a Return Authorization. In either case, re-package the window in the original box and tape the invoice number or return authorization number to the outside of the box.
