I have had a The 56 inch maximum series box bolted into a cube van for 5 years and 250,000 km. Still in great condition. Not a single drawer issue. And the drawers all latch and release real nice and easy. Considering all the tools inside the box fall apart and disassemble themselves as they shake around while traveling, I consider the box very well made. I have a second one and a husky next to each other in the garage and the husky is light duty compared to the maximum. Paid about $1000 for both pieces when they are on sale.
