A Deep Dive into the Enhanced Ventilation, Security, and Weatherproofing of the All-New Version 2.
MilesRunner Inflatable Bed Topper Version 2 (V2), our goal was simple: create a rugged, high-performance truck shell that offers premium features without the "premium" markup seen elsewhere in the industry.
Recently, professional outdoorsman Brian Waters from Brian Waters Outdoors put the V2 through a rigorous real-world test. From a high-pressure water test to a solo installation in the wind, Brian’s review confirms that the V2 isn't just an upgrade—it's a complete evolution in truck bed utility.
One of the most striking takeaways from Brian’s review is the sheer value of the V2. By optimizing our manufacturing and focusing on functional design, we are able to offer the V2 at a price point nearly $1,000 less than comparable high-end inflatable toppers on the market today.
As Brian noted during his setup:

We listened to the truck camping community to turn the V1 into the ultimate V2. Brian highlighted three major areas where the V2 stands alone:

The biggest leap forward is the window system. Unlike basic designs that only offer a "fully open or fully closed" option, the V2 features:
-
Dual-Layer Rear Window: A permanent high-visibility bug screen paired with a heavy-duty zippered clear window.
-
Cab-Side Access: A full-length zippered front window, allowing for airflow and easy access to the truck cab.

2. The New "Rigid-Seal" Security
Instead of relying on standard fasteners that can flap or leak, the V2 introduces a structural rear bar system. This bar zips into the side panels, creating a drum-tight seal against your tailgate. Brian was particularly impressed by the locking points, which allow you to secure your gear more effectively than ever before.

3. Built-In Modular Storage (Molly Loops)
The interior is no longer just empty space. We’ve added Molly Loops along the ceiling and sides. Brian demonstrated how these can be used to hang lighting, tactical gear, or custom storage pouches, turning your truck bed into a organized mobile basecamp.

Based on Brian’s extensive testing, here are the answers to the most common questions from the community:
Q: How does it handle heavy rain?
A: In the video, Brian performed a "flood test" with a hose, soaking the seams and zippers. He found zero water intrusion. The V2 utilizes an integrated rain gasket and architectural aluminum rails that create a superior weather barrier compared to older models.
Q: Can I keep my Tonneau Cover installed?
A: No. To achieve its industry-leading stability and weatherproofing, the V2 requires direct contact with your bed rails via our custom aluminum extrusion system. This ensures the topper stays rock-solid even at highway speeds.
Q: What is the actual interior height?
A: On a standard full-size truck (like Brian’s 6.75' bed), the internal height is 42 inches. This "cab-height" design maintains a sleek, aerodynamic profile while providing enough room for a comfortable sleeping setup.
Q: Is the top load-bearing?
A: Yes. The V2 is rated for a 200 lbs static load. Brian highlighted the external D-rings, which are perfect for securing lightweight gear or attaching side awnings for extra shade.

Whether you are a weekend warrior or a full-time overlander, the MilesRunner V2 offers the protection of a hard shell with the versatility of a portable system.
