Maximize Your Gear: Owl Vans Monster Box & B2 Carrier Install in San Diego

📦 Boost Your Sprinter’s Storage: Owl Vans Monster Box & B2 Carrier Installation in San Diego
December 16, 2025

Key Takeaways
  • Massive Storage Upgrade: The Monster Box adds 40 inches of lockable, weather-resistant storage outside your van.
  • No-Drill B2 Carrier: The modular B2 Carrier system mounts to factory hinges, preserving your Sprinter’s paint and metal.
  • Versatile Mounting: Carry extra fuel, skis, or recovery gear alongside your spare tire.
  • San Diego Ready: Perfect for locking up surfboards at Ocean Beach or recovery gear for Anza-Borrego.
Running out of interior space is the #1 complaint we hear from Sprinter owners. Whether you are packing wetsuits for a morning session at Tourmaline or loading up firewood for a weekend in Julian, the inside of a van fills up fast.
Stop playing Tetris with your cargo. The solution is moving the bulky, dirty, or heavy gear outside the vehicle. At Sprinter Van Solutions, we recently installed the ultimate exterior storage combo: the Owl Vans B2 Carrier paired with the massive Monster Box (40").

What Makes the Owl Vans System the Best Choice?

Why should I choose Owl Vans over other carriers? Owl Vans systems are engineered from lightweight, TIG-welded aluminum, meaning they won't rust in the salty San Diego air. Their unique design mounts directly to the factory 180° or 270° hinges, transferring weight to the chassis rather than the door skin, preventing sheet metal damage.
We love installing these systems because they are modular. Today you might need a giant storage box; tomorrow you might swap it for a bike rack. The B2 Carrier handles it all.

🛠️ The Setup: B2 Carrier + Monster Box

Take a look at the finished installation in our shop. This setup transforms the rear of the van into a utility powerhouse.

In the photo above, you can see the perfect balance. On the left (driver side), we have the B2 Carrier holding the spare tire (essential for off-roading) and a ladder. On the right (passenger side), we’ve mounted the Monster Box.
  • 🔒 Secure: Both the tire and the box are locked down.
  • 🦾 Rugged: The black powder coat finish matches the rugged aesthetic of the Sprinter and resists scratches from brush on narrow trails.

The Monster Box: 40 Inches of Freedom

f you have expensive gear, you worry about theft. Soft bags are great, but they can be slashed. The Owl Vans Monster Box is built like a vault.

🏗️ Built for Abuse

This isn't a flimsy plastic bin. As seen in the close-up below, the craftsmanship is top-tier. Laser-cut logos and precision welding mean this box doesn't just look good—it performs.

🎒 What Fits Inside?

Installing these carriers requires precision. While Owl Vans are "bolt-on," getting the alignment perfect ensures your doors close smoothly and the sensors still work.
Hinge Prep:
We carefully remove the factory plastic trim without breaking the tabs.
Mounting the Uprights:
We bolt the B2 Carrier uprights to the heavy-duty factory hinges.
Alignment:
Before tightening, we ensure the carrier is perfectly vertical so it doesn't look crooked when you're stuck in traffic on the 5 South.
Box & Tire Mount:
We install the Monster Box and spare tire mount, torqueing everything to spec to handle vibrations from washboard roads.
