Two hard-shell roof boxes, nearly identical on the capacity line, and completely different philosophies underneath. That is the whole story here. One prioritizes how much weight you can put up top and how many sides you can load from. The other prioritizes the lid mechanism, the seal, and a stated warranty.
This comparison is built entirely from published listing specifications, not hands-on use. This website does not do hands-on testing, and nothing below describes a product anyone here handled.
Quick Answer
Buy the Goplus Rooftop Cargo Carrier Hard Shell if raw carrying weight and loading access matter most: Goplus rates it at 165 lbs capacity with a dual-sided opening, so you can load from the curb side or the street side depending on where you park. Check Price on Amazon
Buy the Rough Country Rooftop Cargo Box 14.5 Cu Ft if you want the easier lid and the paper trail: Rough Country lists integrated assist struts that hold the lid open, a pull strap for controlled closure, waterproof gasketing, and a 3-year limited warranty. Check Price on Amazon
Here's the thing: the capacity difference between them is functionally noise. Rough Country states 14.46 cu ft, Goplus states 14 cubic feet. That is a fraction of a duffel bag. The real decision is weight rating versus lid hardware.

Design & Build Quality
Both boxes are ABS shells, but the listings describe the material differently, and the difference is worth reading carefully.
Goplus states the box is manufactured from ABS and PC material, with metal lid stiffeners at the bottom that the listing says make the box more stable and safer. PC — polycarbonate — in the shell layup is a specific claim the other listing does not make. Metal stiffeners are a structural detail, and it is a reasonable inference that they exist to resist lid flex on a box this wide, though the listing does not quantify any stiffness figure.
Rough Country describes high-impact UV-protected ABS that resists fading, cracking, and long-term wear. UV protection is the specific word there. If the box lives on the roof year-round in strong sun rather than going into a garage between trips, that stated UV treatment is the more directly relevant claim of the two — Goplus's listing says the box is designed to withstand heavy use in different types of weather conditions, but does not specifically state UV protection.
Rough Country also states the box is made in the USA and backed by a 3-year limited warranty. The Goplus listing supplied here does not state a warranty length or country of manufacture. Note the scope: that means the information is absent from this listing, not that no warranty exists.
Preferred for long-term outdoor exposure and documented backing: Rough Country, on the strength of the stated UV-protected ABS and the stated 3-year limited warranty.
Features & Functionality
This is where the two boxes genuinely diverge, and it is the section that should decide your purchase.
Goplus's headline feature is dual side opening — access from either side of the vehicle. The listing pairs this with a real caution: do not open both sides at the same time, and the key only comes out once the cover is closed and locked. That second detail is a small but genuinely useful anti-forgetfulness design. You cannot drive away with the key in your pocket and the lid unlatched.
Rough Country's headline feature is the lid mechanism. Integrated assist struts hold the lid open for loading, and a built-in pull strap allows controlled closure — the listing specifically frames this as helpful with bulky or heavy items. Anyone who has reached for a roof box lid at full extension on a tall SUV understands the appeal of a strap that brings it back down.
Security language differs in specificity. Goplus states a double-lock design and a security key. Rough Country states a secure locking lid with theft-deterrent protection. Neither listing supplies a lock standard or rating, so a direct security comparison is not established by the supplied data.
Preferred depends on your parking: dual side opening is worth more if you regularly load from a driveway on one side and a curb on the other. Assist struts are worth more if you load alone, load heavy, or drive something tall.
Performance
Honestly, "performance" for a roof box comes down to three numbers: what fits, what it can hold, and what it fits onto.
Volume. Rough Country states 14.46 cu ft with interior dimensions of 65" L x 32" W x 13" H. Goplus states 14 cubic feet but the supplied listing does not state interior dimensions. That published dimension set is a real advantage for planning — 65 inches of interior length tells you whether skis, a folded stroller, or camp chairs will physically lie flat. With Goplus you are buying a volume figure without a published shape.
Load rating. Goplus rates the box at 165 lbs. Rough Country supports up to 125 lbs of evenly distributed cargo. That is a 40 lb gap, and it is the single largest spec difference between these two boxes. Critically, the box rating is not the only limit that matters — your vehicle's roof and your crossbars have their own manufacturer limits, and the lower of the three governs. Neither listing establishes anything about your vehicle's roof capacity.
Still, if you are packing dense gear — tools, canned food, wet camping equipment, a heavy tent — the higher stated rating gives you more headroom before the box itself becomes the binding constraint.
Fit. Goplus publishes the tightest fitment window of the two: 17" to 22.8" wide rack, crossbar width under 3.1 inches, crossbar thickness under 1.0 inches. Measure before you buy. That precision cuts both ways — it is genuinely useful to know, but it also means some racks will not qualify. Rough Country states it installs on most cross rail roof rack systems using included hardware and predrilled mounting points, with no drilling required, which is a broader but vaguer claim.
On aerodynamics, Goplus states a sleek aerodynamic design intended to reduce drag with less noise. No wind noise figure or drag coefficient appears in either listing, so treat that as a design intent claim rather than a measured result.
Preferred for dense loads: Goplus, on its stated 165 lbs rating. Preferred for planning what actually fits: Rough Country, because its interior dimensions are published.
Price & Value
The supplied listings for the Goplus Rooftop Cargo Carrier Hard Shell and the Rough Country Rooftop Cargo Box 14.5 Cu Ft do not state prices or price positioning, so this page makes no claim about where either box sits in the market. Check current price on Amazon for both before deciding, since roof box pricing moves seasonally.
Value is not just the sticker. Rough Country's stated 3-year limited warranty is a quantified commitment, and warranties are one of the few value signals you can actually read off a spec sheet. The Goplus listing supplied here does not state a warranty term.
Against that, Goplus gives you 40 lbs more stated load capacity and a second loading side. If those two things map to how you actually pack, that is real functional value.
Which Should You Buy?
- You park in tight spots and load from whichever side is free. Goplus. Dual side opening is the specific feature that solves this, and no amount of strut assistance replaces it. Check Price on Amazon
- You load alone, and the lid is above your comfortable reach. Rough Country. Assist struts hold the lid open and the pull strap brings it back down, which the listing specifically ties to bulky or heavy items. Check Price on Amazon
- You haul dense, heavy gear. Goplus, at a stated 165 lbs versus 125 lbs — provided your vehicle's own roof limit is not the lower number.
- You need to know exactly what fits before ordering. Rough Country publishes 65" L x 32" W x 13" H. Goplus publishes volume only.
- The box lives on the roof through summer. Rough Country's stated UV-protected ABS speaks directly to that.
- You have unusual crossbars. Measure first. Goplus states hard numbers you can check against a tape measure; Rough Country states broad compatibility without a published range.
How We Research
Every figure on this page came from two source types and nothing else: Amazon Creators API verified product records for both ASINs, retrieved 2026-09-06, and the product listing feature bullets published on each Amazon listing on that same date.
We read both listings line by line, compared the stated figures directly against each other, and flagged where one listing publishes a number the other simply does not. Nobody here installed, loaded, weighed, or drove with either box. Where a spec is absent, we say it is not stated in the supplied listing rather than assuming a value.
For general product safety recalls and consumer guidance, the CPSC and USA.gov consumer protection are worth a look before any large accessory purchase.
Frequently Asked Questions
Which holds more weight, the Rough Country or the Goplus cargo box?
Goplus rates its box at 165 lbs capacity. Rough Country states support for up to 125 lbs of evenly distributed cargo. That is a 40 lb difference in favor of Goplus, though your vehicle's roof and crossbar ratings may be lower and would govern instead.
Is 14.46 cu ft meaningfully bigger than 14 cubic feet?
No. Rough Country states 14.46 cu ft and Goplus states 14 cubic feet — under half a cubic foot apart. Choose on load rating, lid mechanism, and fitment instead.
What is strut assisted versus dual side opening?
Rough Country uses integrated assist struts that hold the lid open plus a pull strap for controlled closure. Goplus uses a dual-sided opening so you can access the box from either side of the vehicle, though its listing warns not to open both sides at the same time.
Will these fit my roof rack?
Goplus states compatibility with 17" to 22.8" wide racks, with crossbars under 3.1 inches wide and under 1.0 inches thick, and says it suits round, square, factory and most aerodynamic bars. Rough Country states it installs on most cross rail roof rack systems with included hardware and predrilled mounting points, no drilling required, but the supplied listing does not publish a crossbar width range.
Are both cargo boxes waterproof and lockable?
Both listings claim weather protection and locking. Rough Country states waterproof gasketing and a secure locking lid. Goplus states a waterproof design with a double-lock design and a security key. Neither listing supplies an ingress-protection rating or a lock standard.
Does either one come with a warranty?
Rough Country states a 3-year limited warranty and says the box is made in the USA. The Goplus listing supplied here does not state a warranty length — that means the figure is absent from this listing, not that no warranty is offered.
What are the interior dimensions of each box?
Rough Country publishes 65" L x 32" W x 13" H. The supplied Goplus listing states 14 cubic feet of capacity but does not publish interior dimensions, so you cannot confirm in advance whether a long item like skis will lie flat.
Final Verdict
If you forced a single pick from the spec sheets alone, the Rough Country Rooftop Cargo Box 14.5 Cu Ft is the more completely documented product: published interior dimensions of 65" L x 32" W x 13" H, UV-protected ABS, waterproof gasketing, assist struts with a pull strap, and a stated 3-year limited warranty. When two boxes are this close on volume, the one that publishes more of its own specifics and backs them with a stated warranty term is the safer buy. Check Price on Amazon
But that verdict flips fast on one variable. If you pack heavy — and 125 lbs disappears quicker than people expect once you add wet gear and tools — the Goplus Rooftop Cargo Carrier Hard Shell with its stated 165 lbs rating and dual side opening is the more capable box for your specific job.

Weigh your typical load and measure your crossbars. Those two numbers decide this, not the cubic feet on the label.
Sources & Methodology
This website did not physically test, load, install, or laboratory-evaluate either cargo box, and it runs no test facility. What informs this page is a close reading of the Amazon Creators API verified product records and the published product listing feature bullets for ASIN B07K75WXYJ and ASIN B0GMYM84TV, both retrieved on 2026-09-06, compared spec against spec with gaps left visibly open rather than guessed at.
For roof boxes specifically, that method takes a reader a long way, because the decisive variables — stated load rating, interior dimensions, crossbar fitment window, opening style, and warranty term — are all things the manufacturer publishes and you can check against a tape measure and your own vehicle's roof limit. What it cannot tell you is durability over seasons or real-world wind noise, neither of which appears as a published figure in either listing.
