Modular Toolbox Systems Compared: DeWalt, Flex, ToughBuilt, Milwaukee Packout, Ryobi and Makita MakTrak

Introduction

Modular toolbox systems promise one thing above all: grab one stack, throw it in the truck, and everything you need arrives with you. The catch is that not every system makes that promise equally well. To find out which ones actually deliver, six of the most widely available platforms were put head to head: DeWalt, Flex, ToughBuilt, Milwaukee Packout, Ryobi, and Makita MakTrak.

This is not a spec-sheet comparison. Each system was loaded the same way, with large tools in the rolling bottom box, midsize tools in the middle box, and bits, blades and small parts in a top organizer. Then each stack ran the same real-world course, loaded and unloaded on a tailgate, pulled across concrete and grass, through doorways, and up and down a long flight of stairs, with a task at the top that required digging into every box. It turns out that hauling a fully loaded stack up open stairs is far harder than most people expect, and that is exactly where these systems separate themselves.

How the Test Worked

The course was designed to mimic a realistic job site scenario: unload from a truck, move the stack across a driveway and yard, navigate two doorways, climb a large staircase, complete a task (running a reciprocating saw using a battery from the midsize box and a blade from the organizer), repack everything, and descend. The clock started the moment the tailgate was touched.

Because every box in every system opens, closes, and latches differently, the test also measured how quickly you can learn each platform and how easy it is to reach what you need when you need it. One lesson that applied to all six: if you keep small or fragile items in a specific arrangement, transport jostles them badly, so some internal organization or padding is worth adding regardless of brand.

DeWalt Modular Toolbox System

DeWalt was the slowest system on the course at 3:00 flat. Part of that came down to setup friction: the telescopic handle needs to be removed to fit under a tonneau cover, and reinstalling it is trickier than it looks because the bottom has to lock in properly or the handle pulls back out. The small tabs used between the organizer and the intermediate box also proved fragile, with the organizer pulling right off during handling.

On the move, the stack pulled fine across concrete and grass, but the wheel profile on the lower box made climbing open stairs genuinely hard work, with each wheel snagging on the tread lip. The connection system also demands attention: everything needs to be clicked back together properly or pieces can separate in transit.

Flex Modular Toolbox System

Flex finished at 2:27, and it handled most of the course without complaint. Like DeWalt, the handle needs to be removed for low-clearance truck beds, and the tabs lock at the bottom the same way, but the boxes nest and click together more easily, and the stack stayed connected throughout. The large wheels rolled over grass, sidewalks and thresholds without trouble, and on flat ground the stack almost works like a dolly.

Stairs were still a workout. The wheel profile is a little better than DeWalt’s, but a loaded Flex stack is heavy, and the camera jarring on the climb tells the story. The organizer only attaches one specific way, so it is worth learning the correct orientation. Overall, a system that nests well and moves confidently once assembled.

ToughBuilt Modular Toolbox System

ToughBuilt tied with Ryobi at 2:43, but it earns strong marks for usability. It easily wins the stackability award: boxes lock in place automatically when stacked, with nothing extra to latch, and the handle’s bottom latch is the easiest of the group, a quick slap and it is locked. A solid, trim build with nothing hanging off the sides, it tracked closely behind on every surface.

Where ToughBuilt really shines is separation: one small lever undoes the boxes from each other, making it one of the quickest systems to both assemble and take apart. The trade-off is the same as most competitors here, you still have to unstack everything to reach the bottom box.

Ryobi Modular Toolbox System

Ryobi matched ToughBuilt’s time, but with more friction along the way. The handle is not removable, so the whole stack has to be tipped sideways to fit under a tonneau cover, which guarantees the contents shift. On the plus side, the link system is very easy to use: set the boxes together and they click in place.

Stairs were the toughest part of the Ryobi run, with the wheel catching under every tread and the climb requiring noticeably more effort. The link system also inspired less confidence, prompting repeated double-checking that the boxes were properly secured, and there is a question of how well the connections hold when the boxes are muddy. More seriously, the top handle began to break during the descent and ultimately twisted off, held in place by only two small screws.

Milwaukee Packout

Milwaukee Packout won the course at 2:20, and it did so with the least drama. Everything clicks together quickly and securely, the stack pulled across grass and over thresholds without issue, and the descent was a matter of guiding the weight down while protecting the door trim. Like the others, the handle is fixed, so the bottom box has to be tipped sideways into a truck with a low cover, disturbing the organized contents.

The main ergonomic criticism applies at the destination: to open the bottom box you have to remove the intermediate box, so reaching deep items means unstacking. Packout does offer drawer variants that solve exactly this problem if bottom-box access matters to you. As a complete package of speed, security, and all-around competence, it took the win.

Makita MakTrak

Makita MakTrak is the design outlier of the group, and it came in second at 2:27. Out of the truck it is about twice as fast as the competition because nothing has to be disassembled; the whole assembly pulls out and you are ready to go. The form factor is larger with a bigger footprint, and the handle has a tendency to collapse on its own, but those are the main gripes.

Where MakTrak excels is stairs and access. The wheels sit more flush with the bottom of the box, letting the stack skate up treads faster than anything else, and the longer body means less bending on the way down. Uniquely, the boxes open from two directions, and the bottom box can be opened without unstacking anything, a genuine time-saver during the task portion of the test.

Overall Buying Advice

Fastest times, slowest to fastest, as recorded on the course: Milwaukee Packout at 2:20, Makita MakTrak at 2:27, Flex at 2:27, ToughBuilt and Ryobi tied at 2:43, and DeWalt at 3:00. But speed is only part of the story. When it came to getting the right tool out at the top of the stairs and repacking quickly, the two systems that made access easiest were Milwaukee Packout and Makita MakTrak.

A few practical takeaways apply across the board. If a removable handle matters for your truck bed, look at DeWalt or Flex rather than Ryobi, Milwaukee or Makita. If stair climbing is a regular part of your day, MakTrak’s flush wheel design and Packout’s overall smoothness stand out. If you hate fiddly connections, ToughBuilt’s auto-locking stack and single-lever release are the friendliest. And whatever you buy, plan on adding internal organization, because every system lets contents shift in transport.

Conclusion

Milwaukee Packout takes the win in this comparison, combining the fastest course time with quick, confident connections. Makita MakTrak is the compelling alternative if bottom-box access without unstacking is a priority, and ToughBuilt is the easiest system to live with day to day thanks to its effortless stacking and release. Match the system to how you actually work, and any of the top three will serve you well.
