Pick the situations that sound like you
Rear hatch stays clear
It passes only if the measured front-crossbar-to-hatch distance is greater than the manufacturer's published clearance requirement.
- Rhino-Rack MasterFit 440L
- Depends
- Yakima SkyBox NX LG
- Better fit
Your factory crossbars are wide
Both models list “Opens from either side” for loading and hardware. Both models show the same result for “Loading and hardware”, so this row won't decide between them.
- Rhino-Rack MasterFit 440L
- Depends
- Yakima SkyBox NX LG
- Better fit
Work with widely spaced bars
At least 36 inches is the verified maximum center-to-center crossbar spread. A separate fit check is still needed for bar width and profile.
- Rhino-Rack MasterFit 440L
- Good
- Yakima SkyBox NX LG
- Better fit
Your roof-load limit is light
Rhino-Rack MasterFit 440L lists “15.5 cu ft. Gear up to 180 cm” for volume and gear length, while Yakima SkyBox NX LG lists “16 cu ft. Gear up to 175 cm”. Treat this as a hard cap on the size or amount that fits in one run. Shape can matter as much as the headline number.

Luggage for a family of four
Either the manufacturer positions the capacity for four campers, or the volume is at least 18 cubic feet. Real fit is still controlled by gear dimensions.

Your roof is on the short side
Rhino-Rack MasterFit 440L lists “24.4 to 36.6 in bar spread” for vehicle measurements, while Yakima SkyBox NX LG lists “24 to 36 in bar spread. 47 in hatch clearance”. Measure your space and mounting points first. This can be a hard limit on fit.
