Ultimate Sprinter 144 Ventilation: New VWD Rear Quarter Double-Sliding & Awning Windows

A great camper van window should do more than simply let you see outside. It should help control airflow, heat, privacy, insects and comfort inside your van. The latest VWD rear-quarter window options for the Mercedes-Benz Sprinter 144" give builders more control over all of those things — without sacrificing the clean, all-glass exterior appearance that makes a finished Sprinter conversion look right.

Van Windows Direct now offers three premium rear-quarter ventilation choices for the 2007–2026 Mercedes-Benz Sprinter 144" Low Roof and High Roof: SL104-DS driver-side double slider, SR104-DS passenger-side double slider, and the SL104-AW driver-side premium awning window.

Meet the VWD SL104-DS & SR104-DS Double-Sliding Sprinter Windows

Traditional sliding van windows usually give you one movable panel and one direction of airflow. The VWD 104-DS takes that idea much further.

Both the SL104-DS and SR104-DS use two independently sliding glass panels. You can open the forward panel, open the rear panel, or open both depending on where you want air entering the van. That makes the design especially useful around beds, rear seating, cabinets and other camper-van layouts where airflow needs change throughout the day.

Why Two Sliding Panels Matter

The advantage is control. Instead of being limited to one opening location, the 104-DS lets you choose where the air enters.

• Open the front section for airflow toward the forward portion of the sleeping area.
• Open the rear section when you want ventilation concentrated farther back in the van.
• Open both when maximum available slider ventilation is the priority.

Pairing the passenger-side SR104-DS with ventilation elsewhere in the van can also help create cross-flow rather than simply allowing air to enter and stagnate in one area.

Built-In Bug Screen + Thermal Privacy Shade

One of the best parts of the 104-DS design is that the interior features are integrated into the window rather than being an afterthought.

The integrated bug screen lets you enjoy fresh air while helping keep mosquitoes and other insects outside. That becomes especially valuable when camping near water, in the mountains, or during warm summer nights when you want the windows open while sleeping.

The integrated thermal privacy shade adds another layer of functionality. Pull it closed when you want privacy, reduced light inside the van or additional separation between the glass and your living space. During the day, simply retract it when you want the view and natural light back.

SL104-AW: Massive Driver-Side Awning Ventilation

For builders who prioritize maximum airflow, the VWD SL104-AW Premium Awning Window takes a completely different approach.

Instead of sliding sideways, a large section of the glass is hinged along the top and opens outward. The resulting ventilation opening measures approximately 37-3/8" wide × 16-5/8" high — substantially larger than the opening found on a conventional van slider.

SL104-AW Key Features

• Designed for the Sprinter 144" driver-side rear quarter
• Fits 2007–2026 Low Roof and High Roof Sprinter models
• Large top-hinged awning opening
• Approximate opening: 37-3/8" W × 16-5/8" H
• 17% solar privacy glass
• Integrated insect screen
• Urethane-bonded automotive installation
• Clean all-glass exterior appearance
• Excellent ventilation for rear sleeping and living spaces

Why the Awning Window Is Driver-Side Only

Placement matters when choosing an outward-opening window.

The standard Sprinter's sliding cargo door is on the passenger side. An outward-opening awning window in the passenger rear-quarter area could create an interference concern when the sliding door travels rearward.

For that reason, the 104-series Premium Awning configuration is offered for the driver-side rear quarter, keeping the large outward-opening panel away from the standard passenger sliding door.

Important: the SL104-AW is also not intended for vans equipped with an optional driver-side sliding door.

Ventilation Even When the Weather Changes

This is where the awning design really earns its place in a camper van. Because the glass hinges from the top, the open panel naturally forms a small canopy over the ventilation opening.

That means an awning-style window can often remain partially open during light rain, allowing airflow when a conventional open slider may need to be closed.

For overnight camping, cooking, warm humid weather or sleeping with several people inside the van, that additional ventilation can make a substantial difference in interior comfort.

The Combination We Love: Passenger Double Slider + Driver Awning

You do not have to choose between a slider and an awning. In fact, combining the two may be the best rear-window ventilation package for many Sprinter camper builds.

What About Double Sliders on Both Sides?

That is another excellent configuration. Because VWD offers the 104-DS for both driver and passenger rear-quarter positions, builders can install matching double sliders on both sides of the van.

Opening sections on opposite sides can create strong cross-ventilation while maintaining the matching appearance of identical window styles.

If you camp primarily in dry climates and want maximum control over exactly where each window opens, dual 104-DS windows are an extremely versatile setup.

Solar Privacy Glass for a Factory-Style Appearance

All three windows use dark 17% solar privacy glass, helping the new ventilation system visually blend with the Sprinter's exterior instead of looking like an added RV window.

The dark glass helps reduce glare, improves daytime privacy and gives the van the streamlined all-glass appearance that many professional and DIY conversions are trying to achieve.

Designed Specifically for the Sprinter 144

These are not generic rectangular RV windows adapted to fit a van. The 104-series windows are designed around the rear-quarter locations of the Mercedes-Benz Sprinter 144" wheelbase.

Fitment includes:

• Mercedes-Benz Sprinter
• 2007–2026 model years
• 144" wheelbase
• Low Roof
• High Roof

Which VWD 104-Series Window Should You Choose?

Choose the SL104-DS if:

• You want a driver-side rear-quarter slider.
• You want two independently controlled openings.
• You want a built-in insect screen and thermal privacy shade.
• You prefer a sliding window instead of an outward-opening panel.

Choose the SR104-DS if:

• You need an opening window that works alongside the Sprinter's passenger sliding-door layout.
• You want integrated screening and privacy.
• You want matching double sliders on both sides of the van.

Choose the SL104-AW if:

• You want maximum rear-quarter airflow.
• You like the ventilation advantages of a large awning-style opening.
• You want the ability to maintain airflow during many light-rain conditions.
• Your driver side does not have an optional sliding door.

Choose SR104-DS + SL104-AW if:

• You want one of the most versatile rear ventilation combinations available.
• You want cross-ventilation across the sleeping area.
• You want both adjustable sliding airflow and large awning-style airflow.
• You camp in varying climates and weather conditions.

Turn the Rear of Your Sprinter Into a Better Living Space

The rear quarter of a Sprinter is where many conversions place the bed, seating, storage or living area — exactly where ventilation matters most.

With the SL104-DS, SR104-DS and SL104-AW, builders no longer have to settle for fixed rear glass or a basic single slider.

Choose two double sliders for exceptional airflow control, or combine a passenger-side double slider with the massive driver-side awning to create a powerful cross-ventilation system built around real-world camper-van use.

Fresh air when you want it. Privacy when you need it. Bug protection while camping. And a clean exterior appearance worthy of a professionally finished Sprinter build.

Frequently Asked Questions

Can I install VWD double-sliding rear windows on both sides of a Sprinter 144?

Yes. The SL104-DS is designed for the driver-side rear quarter and the SR104-DS is designed for the passenger-side rear quarter.

Why isn't there a passenger-side 104 awning window?

The standard Sprinter uses a passenger-side sliding cargo door. Because an awning window opens outward, locating it on the driver side avoids potential interference with the passenger sliding door.

Do the VWD 104-DS windows include screens?

Yes. Both double-sliding models include an integrated bug screen.

Do the double sliders include privacy shades?

Yes. The SL104-DS and SR104-DS include an integrated thermal privacy shade for privacy, light control and added interior comfort.

Can the SL104-AW be used when it is raining?

The top-hinged awning configuration helps shield the opening and can allow ventilation during many light-rain conditions. As with any opening window, wind direction and severe weather should always be considered.

What is the best combination for maximum Sprinter ventilation?

A popular high-airflow configuration is the SR104-DS double slider on the passenger side combined with the SL104-AW premium awning on the driver side. This creates ventilation openings on opposite sides of the rear living area and gives you two different ways to control airflow.
