Description:
The Trenta Aluminum Storage Box utilizes a fully welded 3mm aluminum body to deliver maximum impact resistance and durability. Unlike hybrid or riveted boxes, this unit features a seamless welded construction that eliminates the need for body seals, ensuring water cannot enter through panel joints even after years of vibration and off-road use.
Designed for a direct fit to the Sprinter gear rack, the box’s vertical profile is optimized for oversized gear. With a usable internal height of 75 inches (1905 mm), it securely houses skis, snowboards, golf bags, and other long equipment that does not fit in standard square cargo boxes. This model features two removable internal panels and four door-mounted L-tracks, allowing you to secure smaller items or customize the interior layout to fit your specific loadout.
The door utilizes a continuous rubber seal to create a watertight and dustproof barrier. This effectively blocks high pressure water spray and rain at highway speeds. For security, a robust locking handle keeps the door tightly closed and your gear safe.
FAQ:
1. Will mounting a box this size damage my rear door hinges or cause the door to sag over time?
The box weighs 99 lbs. While the door hinges can support this load, you must be careful not to exceed your gear rack's weight limit. If you are using our gear rack, the limit is 180 lbs, leaving roughly 80 lbs for gear. If you use another brand, please verify their load limit first.
2. Does the box obstruct the rear parking sensors or cause the blind-spot monitoring system to beep constantly in reverse?
This depends on how high you mount it. If it is mounted too low, it might trigger the sensors. You can fix this by mounting the box higher up or adjusting the angle of your sensors.
3. Is this box compatible with existing Sprinter carrier plates from brands like Owl Vans, Aluminess, or other standard panels?
Due the larger size, this box is not compatible with some gear racks. Please double check the measurements or contact us before purchasing to ensure it fits your setup.
4. Is the weatherproof seal capable of withstanding high-pressure car washes and driving rain at highway speeds?
Yes, it is waterproof. The rubber seal keeps water and dust out, even during heavy rain or car washes.
5. Does the box interfere with the rear door opening fully (180° vs 270° hinges) or hitting the side of the van?
This depends on your gear rack settings. After installing, check the door opening angle carefully to make sure the box doesn't hit the side of the van. You may need to install a limit stop on your door hinge or use a check strap to stop the door earlier.
6.How secure is the locking mechanism against theft for high-value items?
The box features a dual-point locking system to resist prying, with the option to add secondary padlocks for double security. The aluminum construction further reinforces the unit against forced entry.

FAQs
Please read our FAQs page to find out more.
Do your products work with all van models?
Yes! Most of our parts specify compatibility with Mercedes Sprinter, Ram ProMaster, and Ford Transit platforms. Check each product page for exact fitment. Still unsure? Shoot us a message — we’re happy to confirm before you buy.
How long does shipping take?
Orders usually ship within 2–3 business days. Transit time depends on your location, but most U.S. customers receive their order within 5–7 days. You’ll get tracking info as soon as it ships.
Some items may ship separately depending on vendor, inventory, or warehouse location — so you might receive multiple packages for a single order. You’ll get tracking numbers for each one.
Do you offer returns or exchanges?
Yes — we accept returns within 30 days of delivery for unused, uninstalled products in original packaging. Just contact us and we’ll help get the process started.
Please note: Some products ship directly from our vendor partners, and in those cases, the final decision on return eligibility is made by the vendor. We’ll always advocate for you, but policies may vary slightly by brand.
Can I pick up my order locally?
At this time, all orders ship from our warehouse — we don’t offer local pickup. If you’re working with our van build team, parts can be coordinated into your build directly.
Do you offer bulk discounts or fleet pricing?
Yes! We work with upfitters, outfitters, and van builders nationwide. Reach out to us with what you need and we’ll get you a custom quote.
