We customized the dump body for sand transport, and with the optional hydraulic hoist, unloading is faster than ever."Purchase Date: September 2024 | Usage Period: 8 months

"After comparing several models, we chose the Pro Model of the HOWO dump truck for our granite quarry. With 326 HP and a 14.3-ton load capacity, it outperforms older units in our fleet. The all-terrain 6x4 configuration and enhanced suspension make daily runs over rocky ground smooth and safe. Fuel consumption is reasonable for the workload, and tire life has exceeded expectations thanks to the heavy-duty treads."Purchase Date: February 2025 | Usage Period: 3 months
⭐⭐⭐⭐☆ Farhana Rahman - Independent Contractor, Rajshahi
"I run a small demolition and land-clearing business, and this truck has been a solid investment. The steel body shows no signs of wear after hauling debris and soil for five months. I appreciate the panoramic cab visibility—it makes tight spaces much safer to navigate. Only downside: the manual transmission takes some getting used to, but now I prefer it for control."Purchase Date: November 2024 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Anwar Hossain - Mining Supervisor, Sylhet
"We operate in a high-moisture, uneven terrain environment, and the HOWO dump truck has proven incredibly reliable. The Euro 2 compliance was a requirement for our site, and this model delivers without sacrificing power. We added LED lighting for night shifts, and the reinforced mirrors are a big plus for safety. Zero breakdowns in seven months—rare for heavy machinery in our conditions."Purchase Date: October 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ Nasir Uddin - Residential Builder, Khulna
"Used this for transporting gravel and fill across multiple home development sites. The 11-ton base model is perfect for mid-sized jobs—doesn’t feel overkill but still handles loads efficiently. The cab is roomy and comfortable, which matters when drivers are on-site all day. Would’ve liked more customization options upfront, but the supplier helped us retrofit a conveyor belt later."Purchase Date: January 2025 | Usage Period: 5 months

"The HOWO ZZ3257N3647A stands out in the 11–20 ton segment due to its balanced power-to-compliance ratio. Its Euro 2 engine may not be the most advanced, but in markets like Bangladesh, it offers the right mix of performance and regulatory acceptance. The 6x4 drivetrain and steel construction make it one of the most durable options under $100K."

"For contractors balancing cost, durability, and versatility, the HOWO dump truck is an excellent choice.

"Great truck for debris removal. Steel body is tough, and the cab is roomy. Only note: fuel use is on the higher side during continuous operation. Still, durability outweighs this minor drawback."
