How each alternative compares
GarveeTech 12 cu ft Dual-Side Opening Roof Box
The GarveeTech 12 cu ft Dual-Side Opening Roof Box has a smaller interior (12 cu ft) than the JEGS 18 cu ft box, so it holds less gear. However, it opens from both sides, making loading easier on either side of your vehicle. Its load capacity is 165 lb, which is 55 lb higher than the JEGS 110 lb limit. The GarveeTech weighs 39 lb, slightly more than the JEGS 35.5 lb. It measures 54.3" L x 31.5" W x 13.4" H, making it shorter, narrower, and taller than the JEGS. Choose the GarveeTech if you need dual-side access and can carry heavier items, but you will sacrifice overall cargo volume.
DNA Motoring 13 cu ft Hard Shell Roof Box
The DNA Motoring 13 cu ft Hard Shell Roof Box offers 13 cu ft of capacity, 5 cu ft less than the JEGS 18 cu ft box. Its load capacity is the same 110 lb. It opens on both sides, unlike the JEGS rear-only opening. The DNA box is 56.3" L x 36.8" W x 16.3" H, so it is shorter, narrower, and taller than the JEGS. It is lockable and installs without tools, matching the JEGS ease of setup. Pick the DNA Motoring box if you want a premium, compact box with double-side access and do not need the full 18 cu ft of the JEGS.
Maxsa Innovations 17 cu ft Hard Shell Cargo Box
The Maxsa Innovations 17 cu ft Hard Shell Cargo Box has 17 cu ft capacity, 1 cu ft less than the JEGS 18 cu ft box. It weighs 35.3 lb, nearly identical to the JEGS 35.5 lb. Its load capacity is 165 lb, higher than the JEGS 110 lb. The Maxsa measures 55.1" L x 35" W x 16.1" H, making it shorter, narrower, and taller than the JEGS. It is a hard shell with a locking system. Choose the Maxsa if you want a slightly smaller, lighter box that can carry heavier loads at a lower price point than the JEGS.
PM Performotor 11 cu ft Hard Shell Cargo Box
The PM Performotor 11 cu ft Hard Shell Cargo Box holds 11 cu ft, which is 7 cu ft less than the JEGS 18 cu ft box. Its load capacity is not listed, but it is designed for lighter loads. It is 53" L x 34" W x 15" H, smaller in all dimensions than the JEGS. It is lockable and installs without tools. The PM Performotor is best for compact sedans or small SUVs where the JEGS box may be too large. Pick this box if you need a small, weatherproof carrier and do not require the volume or weight capacity of the JEGS.
Ausum Motor 14 cu ft Dual-Side Box
The Ausum Motor 14 cu ft Dual-Side Box has 14 cu ft capacity, 4 cu ft less than the JEGS 18 cu ft box. Its load capacity is 110 lb, matching the JEGS. It opens on both sides, unlike the JEGS rear-only opening. The Ausum weighs 45 lb, which is 9.5 lb heavier than the JEGS. Its dimensions are not fully listed, but it is a compact box. It features a weather-sealed hard shell and central lock. Choose the Ausum if you want dual-side access and a compact size, but be aware it is heavier and holds less volume than the JEGS.
JEGS 18 cu ft Hardshell Rooftop Carrier
The JEGS 18 cu ft Hardshell Rooftop Carrier (model 555-90109) is also 18 cu ft like the original JEGS box, but it opens on both sides instead of only the rear. It weighs 35 lb, slightly less than the original 35.5 lb. Its dimensions are 57" L x 38.5" W x 17.8" H, making it shorter, narrower, and taller than the original JEGS box. It is a hard shell and mounts to the roof. Pick this JEGS variant if you want the same 18 cu ft capacity but prefer dual-side access for easier loading from either side of your vehicle.
