Description

Expand your vehicle’s carrying capacity with this 450L rear-mounted cargo box, designed for year-round travel, touring and outdoor adventures. Ideal for campervans, motorhomes, SUVs, 4x4s and electric vehicles, this versatile rear storage solution delivers generous extra space without the drag and inconvenience of a traditional roof box.

Whether you’re heading off on a UK touring trip, carrying camping gear, transporting bikes and outdoor equipment, or packing for a family holiday, this tow bar-mounted cargo box adds practical storage exactly where you need it.


450 Litres of Practical Rear Storage

  • Outdoor gear

  • Folding chairs and awnings

  • Sports equipment

The rear-mounted design keeps roof space free for solar panels, roof tents, or additional accessories — ideal for campervan and van life setups.


Aerodynamic & EV-Friendly Design

  • Improve motorway efficiency

  • Reduce wind noise compared to roof boxes

A smart choice for EV owners and efficiency-conscious drivers.


Low-Profile, Easy-Load Design

  • Touring couples

  • Families

  • Older travellers

  • Frequent road trippers


Secure Locking System with Visual Confirmation

The integrated locking system features separate locking and opening functions and clearly indicates when the box is securely closed, giving confidence on long journeys.


Durable & Weather-Resistant Construction

Built to withstand British weather conditions, the box protects contents from:

  • Rain and road spray

  • Dirt and debris

  • Long motorway journeys

Integrated rear lights improve safety, visibility and road compliance.
