Will the three-door rear cover of a heavily modified pickup truck leak water?

Time:2026-06-10Author: Mengtu Auto Parts

The newly launched 3-door high canopy for pickup trucks features bold lines and a distinctive rugged appearance, winning great popularity among pickup enthusiasts who love travelling and vehicle modification.

Adopting a split assembly structure, it avoids the large packaging size of traditional integrated canopies, effectively cutting shipping volume and transportation costs. When not in use, it can be disassembled for storage to save space. The modular design also enables flexible DIY modification: each component is replaceable individually. You may fit side doors with operable windows for ventilation, fully enclosed doors or fixed glass doors for complete sealing, and even change the exterior decorative panels on doors. Damaged parts can be replaced separately, delivering outstanding flexibility.

With three accessible sides, the canopy is highly practical. It boasts a strong load-bearing capacity with a dynamic load rating of 300kg. Multiple reserved expansion ports allow mounting tents, luggage and other accessories.

Many people wonder whether the 3-door canopy is waterproof.

The performance varies greatly among manufacturers. Though it has a simple outline and straightforward structure, which may seem easy to replicate with bending machines, laser cutters, welding equipment and basic metalworking skills, its production actually demands solid technical expertise and skilled workmanship. Manufacturers need to conduct professional design on structural rationality, mechanical performance and fatigue resistance. Meanwhile, workers must possess extensive practical experience. The split structure requires extremely high machining precision. Unreasonable design or inaccurate manufacturing will lead to defects and assembly problems.

Mengtu has specialised in manufacturing pickup canopies for 10 years, with mature craftsmanship and core technologies. Our 3-door canopies fully meet the basic waterproof requirement — a fundamental standard for such products.

Some non-professional automotive suppliers have entered this market simply by copying the appearance without mastering the core technology, resulting in uneven product quality. Many car owners have unfortunately purchased leaky products. Therefore, it is advisable to choose reliable brands carefully.
