Types

Case: Hard-sided cargo pods are safer. They usually come pre-assembled and need just clamps, U-bolts, or other mounting gear to attach to your automobile. The latch of a box carrier is usually lockable. Since boxy pods block airflow around your automobile, they may be noisy and waste petrol.

Soft-sided bags have straps to attach to your vehicle’s roof, unlike hard-sided bags, which need a roof rack. Many bag carriers cost $100 or less. Most soft-sided pods are watertight, but they’re not safe.

These enormous metal baskets on the roof rack may be secured with straps, bungee cords, or ropes. They’re cheap and don’t block wind when empty. Any item in a basket is susceptible to weather and theft.

Specs

Make sure the load carrier fits in your vehicle by measuring its length. If it extends beyond the windshield, it may block your view or drastically increase wind drag, causing noise and poor fuel efficiency. If it exceeds the roof’s back, it may block the hatch. Think about its height too. A lower-profile variety (11 inches or less) may be better for garage parking than 15 to 18 inches.

Form and Maintainability: Skis and golf gear need a longer cargo container. Get a tall cargo crate for your luggage. For a normal load, be in the carrier’s 8–22 cubic foot range.

Consider how much you’ll lift to install the carrier. Heavy versions weigh approximately 60 pounds, while smaller ones weigh 15 pounds. Next, examine the carrier’s weight capacity to ensure it can take your load. Finally, check your vehicle’s manual for dynamic load limits. Some carriers can carry 175 pounds, but your car’s roof may not support it.

Features

Mechanical shutter/door. Box carriers may be single-, double-, or rear-entry. The best choice is a dual-sided one with driver and passenger access. Low-cost airlines restrict access to the rear or one side. A cargo bag’s zipper usually opens in three ways. For maximum water protection, choose a bag with a full-cover rain flap and a robust zipper.

Internal closet. Cost-effective transportation is typically empty boats. greater expensive models have greater storage features. Felt liners prevent scratches, while inner tie-down points secure goods. Some pricey transport containers include LED lighting.
