Buying Guide: Key Purchase Considerations
When choosing trailer leveling blocks, consider weight capacity, terrain versatility, and ease of use. Interlocking designs improve stability on loose ground, while higher block counts allow greater customization for uneven sites. Material quality matters: UV resistance, impact strength, and weather durability extend the life of the blocks in outdoor conditions. A carrying bag is a practical addition for portability, and some sets include a bubble level or top blocks to simplify leveling accuracy.
- Capacity and compatibility: Verify that the blocks can support your trailer’s weight and tire size. Larger rigs may require blocks with higher load ratings and wider footprints.
- Height range and stackability: Ensure the system offers the height adjustments you need, from partial to full leveling, depending on ground conditions.
- Interlocking feature: Interlocked blocks reduce movement during leveling and while parked, enhancing safety.
- Materials and durability: Look for reinforced polymers or high-density plastics with UV resistance for outdoor use.
- Portability: A carrying bag or integrated handles helps transport and storage on trips.
Usage tips for effective leveling
- Inspect the ground for soft spots; place blocks on firm soil or compacted surfaces when possible.
- Place blocks and drive onto them slowly to achieve the desired height increments.
- Use a bubble level to verify levelness along the fore-aft and side-to-side axes.
- Stack blocks evenly and avoid twisting the wheel as you drive onto them.
