ATV riders often hit the same wall: where to put a helmet, rain gear, trail tools, and a day's worth of supplies without leaving everything exposed on a rack. A rear passenger seat cargo trunk can clear up that space, but it's worth asking whether the extra storage justifies the added setup. The TCMT 82L rear passenger seat cargo storage helmet trunk box is one option that promises to turn the rear seat into a covered cargo space.
Quick Verdict
At USD 249.50, this trunk gives you a single large box with a universal fit for ATVs and a 1-year manufacturer warranty. It's a practical way to keep bulky gear out of the weather, but the setup step is significant.
Who It Suits
This trunk is aimed at ATV riders who regularly carry a helmet, a small cooler, a backpack, or trail tools. It also makes sense if you prefer one fixed storage spot over strapping bags to a rack. Because the trunk takes over the rear passenger seat area, it's best suited for riders who don't need that space for a passenger. If you're a solo rider with gear-heavy days, this setup gives you one spot to keep everything.
What Stands Out from the Listed Details
The headline feature is the 82-liter capacity. That's enough for a helmet plus loose gear, and the box is made from LLDPE. It comes in black and is listed as new.
Meaningful Trade-offs
The biggest trade-off is the mounting method: the box requires drilling holes for installation. Measure twice and plan the hole locations before you start. Because the fit is universal, you'll need to position it carefully against your ATV's rear passenger area to make sure it aligns well. The product also carries a California Prop 65 warning, which is worth factoring into your decision.
82L ATV Rear Passenger Seat Cargo Storage Helmet Trunk Box Luggage Lounger
This black, 82-liter rear passenger seat cargo trunk from TCMT is built from LLDPE. It's the right pick if you need a large enclosed cargo volume for helmet and gear storage; the trade-off is the drill-based installation and a California Prop 65 warning.
Bottom Line
If you need a large enclosed storage box for your ATV and you're comfortable with a permanent mount, this rear passenger cargo trunk is a straightforward option at USD 249.50. It gives you a big, dedicated cargo space to keep your gear out of the weather.
