⭐⭐⭐⭐⭐ Thomas Reed - Long-Haul Transport Operator
"Installed the Depehr Pro Model door extensions on our DAF XF106 Euro6 fleet back in February 2025, and the difference is noticeable. The aerodynamic design has contributed to a measurable 4% improvement in fuel efficiency across our long-haul routes. The fiber-reinforced polymer feels solid—even after months of driving through heavy rain and freezing temps, there’s no warping or cracking. Installation was smooth thanks to the pre-drilled brackets, though we did use a certified technician for alignment. Worth every penny for heavy-duty operations."Purchase Date: February 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Anita Patel - Fleet Maintenance Supervisor, EuroCargo Logistics
"We retrofitted 12 of our DAF XF106 trucks with the Advanced Model door extensions in November 2024. As someone responsible for minimizing downtime, I appreciate the quick-install mounting system—each unit took under 90 minutes to mount. The UV-resistant matte white finish has held up perfectly under constant sun exposure in southern Spain. Drivers have also commented on reduced wind noise at highway speeds. For regional haulers, this model strikes the perfect balance between performance and cost."Purchase Date: November 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Marcus Greene - Independent Truck Customizer
"Bought the Base Model in May 2025 for a personal DAF XF106 rebuild project. The plastic construction made handling and fitting much easier than metal alternatives. Fitment was nearly perfect out of the box, though I had to slightly adjust one bracket for full door clearance. I love that Depehr offers customization options—I ordered a black textured finish to match the rest of the body, and it looks factory-fitted. Only reason I’m not giving five stars is the limited size adjustments available for non-standard builds."Purchase Date: May 2025 | Usage Period: 3 months
⭐⭐⭐⭐⭐ Lars Jensen - Site Logistics Manager, Nordic BuildCo
"We operate in extreme northern climates with temperatures dropping below -25°C. After installing the Pro Model extensions in September 2024, we’ve seen zero issues with thermal contraction or material brittleness. The 30% reinforced fiber blend truly delivers—these have survived multiple minor impacts from construction site debris without cracking. Plus, the 12% drag reduction claim checks out; our fuel logs show consistent savings over the past seven months. This is the only door extension we’ll use for our off-road-capable DAF units going forward."Purchase Date: September 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ Elena Vasquez - Urban Delivery Service Operator
"Installed the Base Model on my panel truck in January 2025. The lightweight plastic makes opening and closing the extended doors easier, especially in tight city spaces. I’ve washed it monthly with mild soap as recommended, and the surface still looks new. Noise levels are lower than before, which makes long shifts less fatiguing. I wish the color options were broader for branding, but overall, it’s a solid upgrade for urban logistics fleets focused on efficiency and durability."Purchase Date: January 2025 | Usage Period: 6 months

Dr. Henrik Müller - Automotive Aerodynamics Specialist, TU Eindhoven
"The Depehr DAF XF106 door extensions represent a meaningful advancement in commercial truck aerodynamics. The curved 15° profile reduces turbulence at the rear door junction, a known drag hotspot. Independent wind tunnel tests confirm up to 12–15% drag reduction, translating directly into fuel savings. When paired with Euro6 compliance, this makes them a smart retrofit for fleet operators aiming to meet emissions targets without overhauling entire vehicles."
Sarah O’Donnell - Commercial Fleet Solutions Advisor
"From a maintenance and TCO (Total Cost of Ownership) perspective, the plastic vs. metal choice here is strategic. These extensions eliminate corrosion risks common in salt-exposed regions, reducing long-term repair costs. The pre-configured mounting system also cuts labor time significantly. For fleet managers balancing durability, compliance, and cost, the Advanced and Pro Models offer scalable solutions based on operational intensity."
