- Advantages:
- Weather protection for goods.
- Secure and tamper-resistant.
- Challenges: Not suitable for temperature-sensitive, over-sized, or odd-shaped items.
2. Refrigerated Trailers (Reefers)
- What They Are: Insulated trailers equipped with cooling units.
- Best For: Perishable foods, pharmaceuticals, flowers, and other temperature-sensitive cargo.
- Advantages:
- Strict climate control maintains product integrity.
- Challenges: Higher costs due to refrigeration, fuel for units.
3. Flatbed Trailers

- Advantages:
- Easy loading from sides or top using cranes or forklifts.
- Perfect for wide or tall items.
- Challenges: Cargo requires securing and tarping for weather protection.
4. Step Deck (Drop Deck) Trailers
- What They Are: Similar to flatbeds but with a lower deck height after the front section.
- Best For: Tall cargo that would exceed height restrictions on a standard flatbed.
- Advantages:
- Can handle taller loads while maintaining legal height limits.
- Challenges: Special equipment may be needed to load and unload.
5. Double Drop Trailers
