Buying Guide: Key Purchase Considerations
- Material and durability: Aluminum topsiders with diamond tread provide corrosion resistance and long-term endurance. Look for 0.100 inch thickness for heavy-duty use, and consider thicker tubs for added rigidity.
- Weather sealing and security: A strong locking mechanism (die-cast T-handles or similar) combined with a replaceable gasket sealing system helps protect against theft and the elements. Dual gas shocks and aircraft cables improve door operation and safety.
- Installation and fit: No-drill mounting options save installation time and preserve the truck’s structure. Ensure the width, height, and depth match your flatbed dimensions and cargo needs.
- Access and organization: Full 90-degree opening or dual flip-up doors facilitates easy loading and unloading. Internal shelves or tiers can optimize tool organization on larger jobs.
- Storage space vs. bed usability: Wider topsiders maximize capacity, but consider bed access for bulky items. Some models provide two-tier storage or lower/upper shelving to separate tools from larger cargo.
- Brand and warranty: Reputable brands like Buyers Products and UWS offer integrated mounting hardware and customer support. Check warranty terms and replacement parts availability.
- Maintenance: Regularly inspect seals, hinges, and latches for wear. Clean aluminum surfaces to prevent oxidation and maintain a clean look on fleet vehicles.
In summary, the best topsider selections balance heavy-grade aluminum construction, secure locking mechanisms, weather protection, and installation simplicity. Contractors and fleet managers should consider bed dimensions, tool inventory size, and access preferences when choosing among these options. The reviewed models cover a range from compact to wide configurations, ensuring compatibility with various flatbed setups and job-site demands.
