Quick take
Riders adding powersports luggage storage to an ATV or UTV often start with the same question: do you want a simple rack-mounted cargo box or a rear trunk that can also work as a passenger lounger? This comparison covers one universal front/rear rack box, one universal rear trunk, and two Kolpin rear passenger seat/helmet trunks. The right choice depends on your rack style, how much gear you carry, and whether you need the storage to double as a seat. The listed prices range from the low end to the high end of the group, so the decision is more about matching the mount and layout to your machine than about making a minor feature tweak.

Product notes
75L ATV Rear Trunk Cargo Storage Box Rack Luggage Case for UTV Can-am Universal
This is the universal rear trunk for riders who want one box that can move across a range of machines. The listing calls out compatibility with Argo, Honda, Kawasaki, Odes UTVs, Polaris, Suzuki, and Yamaha, and the material is listed as LLDPE. The mounting style is screw-on, so it works as a fixed rear cargo box rather than a quick-swap front/rear rack basket. The black finish keeps the look consistent with most OEM racks. Choose it when your priority is broad ATV/UTV fit in a single rear trunk and you do not need the passenger-lounger layout of the Kolpin boxes.
Universal ATV UTV Quad Front / Rear Basket Rack Cargo Storage Box 14GAL(52L
If you want a storage box that can sit on the front or rear rack, this universal model is built for that. It offers a 14-gallon (52-liter) capacity in a compact 29 x 13 x 9-inch footprint, and the LDPE material is described as scratch-resistant to handle trail debris. The design is a rack-mounted cargo box rather than a rear passenger seat or lounger, so it will not add a seat to your machine. For riders who need to carry tools, drinks, and clothes without adding a big rear trunk, this box keeps the cargo space simple and the rack placement flexible. If your trails involve tight storage needs, the compact footprint is a practical fit.
Kolpin ATV Rear Passenger Seat Cargo Storage Helmet Trunk Box Luggage Lounger (4438)
This Kolpin model turns the rear rack into a spot for both cargo and a passenger-lounger. It is described as a heavy-duty, rotomolded, UV-stabilized LLDPE trunk that opens in the rear with access to arm cavities, and it comes with mounting hardware for tubular-style racks. That hardware is worth paying attention to: the listing warns that Polaris and Can-Am racks will require custom mounting, such as drilling holes or using Polaris Lock & Ride devices. If you have a tubular rack, the included U-bolts and sealing washers are your intended path; if you ride a Polaris or Can-Am, plan for modification before you order. This is a rear-mounted cargo solution with a seat-like profile.
Kolpin ATV Rear Passenger Seat Cargo Storage Helmet Trunk Box Luggage Lounger (4457)
This version of the Kolpin rear luggage lounger is specified with a 31-gallon (117-liter) capacity, enough room for two full-size adult helmets, plus a seamless hinge and gutter design to keep contents dry and dust-free. Heavy-duty rubber draw latches, integrated padlock holes, and removable no-slip seat pads round out the layout. The listing also notes it is made in the USA with global materials. Like the other Kolpin model, the mounting hardware is intended for tubular-style racks, and the description flags that Polaris and Can-Am racks need custom mounting. Choose this variant when you need the extra volume and want the seat-pad and lock-ready details without losing the rear passenger/lounger function.
Final recommendation by use case
Start with your rack and your cargo style. If you want a universal rear trunk that can sit on a range of ATV/UTV makes, the 75L ATV Rear Trunk Cargo Storage Box Rack Luggage Case for UTV Can-am Universal is the direct choice. If you want a smaller, front- or rear-rack cargo box with a compact footprint, the Universal ATV UTV Quad Front / Rear Basket Rack Cargo Storage Box 14GAL gives you that flexibility. For a Kolpin rear passenger seat/helmet trunk, the 4438 model handles tubular racks with included hardware, while the 4457 model includes 31-gallon capacity, two-helmet fit, and features like padlock holes and no-slip seat pads.
