Capacity, Build, and Security Compared
Load capacity
The CURT 18145 offers a higher maximum load capacity of 500 lb, while the CURT 18110 is rated for 300 lb. This 200 lb difference matters if you plan to haul heavy items like large coolers, toolboxes, or multiple pieces of luggage. The 18145 allows you to carry more weight on the hitch, provided your vehicle’s hitch receiver also supports that limit. The 18110 limits you to 300 lb. If your cargo is generally lighter, both models work, but the 18145 provides a higher safety margin for heavier loads.
Shell type
The CURT 18110 is a flat tray-style carrier with a mesh base, whereas the CURT 18145 features a basket design with 6-inch tall sides. The tray design of the 18110 exposes cargo to the elements, requiring you to use tarps or bags for weather protection. The basket sides of the 18145 help contain smaller items and keep them from shifting or falling out during transit. The elevated sides also offer better visibility of the cargo area. If you need to secure loose gear or want some protection from rain, the basket style is more practical than the open tray.
Build quality
Both carriers are constructed from heavy-duty steel with a black finish. The CURT 18110 uses a two-piece steel tray with an E-coat and carbide black powder coat for durability. The CURT 18145 is made from tubular steel. Both finishes are designed for outdoor use and resistance to corrosion. The 18110 includes integrated tie-down openings around the tray for straps or nets. The 18145 includes built-in reflectors for increased safety and visibility at night. Both models require periodic inspection of hardware to ensure components remain secure during travel.
Compatibility
Both the CURT 18110 and CURT 18145 are designed to fit both 1-1/4-inch and 2-inch hitch receivers. Each model includes a sleeve adapter to accommodate the different receiver sizes. You must verify your vehicle’s receiver opening and pin-hole alignment before installation. The 18110 has a 1-1/4-inch shank with the adapter. The 18145 also uses an adapter sleeve for mounting. This flexibility ensures that both carriers can be used on a wide range of vehicles, regardless of whether your hitch is the smaller or larger standard size.
Dimensions
The CURT 18110 measures 48 inches in length and 20 inches in width, providing a larger surface area for flat items. The CURT 18145 is slightly shorter at 46-1/2 inches in length but narrower at 17-1/2 inches in width. The 18110 is better for long items like kayaks or lumber if secured properly. The 18145’s narrower profile may be easier to fit on some vehicles or in tight spaces. The 18110 tray height is 3.5 inches, while the 18145 basket sides are 6 inches tall. Choose based on the shape and size of your typical cargo.
Which CURT Hitch Carrier Fits Your Needs
Heavy hauler needing max weight rating
The CURT 18145 supports up to 500 lb, which is 200 lb more than the 18110. This higher capacity is essential if you carry heavy gear like toolboxes or large coolers. The tubular steel build and 6-inch tall sides also help keep those heavier items secure during transit without exceeding limits.
User prioritizing flat surface for gear
The CURT 18110 features a wide 48-inch by 20-inch steel tray. This flat mesh base allows you to distribute weight evenly across a larger area. Integrated tie-down openings let you secure cargo nets or straps directly to the frame, making it ideal for flat items like luggage or camping pads.
Driver valuing built-in safety features
The CURT 18145 includes built-in reflectors to increase visibility while driving. This safety feature is absent from the 18110 model. Combined with its 500 lb capacity and tubular steel construction, it offers a secure, visible option for hauling cargo on the back of your vehicle without requiring additional aftermarket accessories.
