### **Pros and Cons of buying a RealTruck SL54020 Undercover Select Folding Bed Tonneau Cover**

#### **Pros**

1. **Durability and Weather Resistance** The SL54020 is constructed with high-quality materials, including UV-resistant fabric and reinforced stitching, which helps protect against rain, snow, and debris. The folding design ensures it remains secure even during high-speed driving.

2. **Easy Installation and Removal** Unlike fixed tonneau covers, this folding model is designed for quick deployment and storage. It can be easily folded and tucked under the truck bed when not in use, making it convenient for loading or unloading cargo.

3. **Space Efficiency** Since it folds flat, it doesn t take up additional storage space in the truck bed when not needed. This is particularly useful for those who frequently switch between covered and uncovered use.

4. **Good Visibility and Access** The folding design allows for full access to the truck bed when open, making it ideal for transporting large or awkwardly shaped items. The cover doesn t obstruct the bed s functionality when folded.

5. **Lightweight and Easy to Handle** Compared to some rigid tonneau covers, this folding model is relatively lightweight, reducing strain when opening or closing it manually.

6. **Compatibility with Various Truck Beds** The SL54020 is designed to fit a range of truck bed lengths (typically 5.4 feet), making it a versatile option for many pickup trucks.

7. **Affordable Compared to Fixed Covers** Folding tonneau covers are generally less expensive than hard-shell or roll-up models, offering a balance between cost and functionality.

#### **Cons**

1. **Less Protection Than Fixed Covers** While it provides some weather resistance, a folding cover is not as secure as a fixed or roll-up tonneau cover. It may not fully shield cargo from heavy rain, snow, or strong winds, especially if not fully sealed.

2. **Manual Operation** Unlike motorized or spring-assisted covers, this model requires manual effort to open and close. This can be tiring if used frequently, especially in large trucks or under adverse weather conditions.

3. **Potential for Loose Ends** If not properly secured, the folded edges of the cover could flap in the wind, creating noise and potentially obstructing visibility. Some users report that the cover may not stay perfectly flat when folded.

4. **Limited Cargo Protection from Theft** Unlike a fully enclosed tonneau cover, this model does not deter theft as effectively. Cargo remains visible and accessible when the cover is folded.

5. **Durability Concerns Over Time** While the materials are generally sturdy, prolonged exposure to UV rays, salt, or abrasive elements (like sharp cargo) could lead to wear and tear, reducing the cover s lifespan.

6. **Not Ideal for Long-Term Storage** If left folded in the bed for extended periods (e.g., during winter), the fabric may become brittle or develop mold/mildew if exposed to moisture.

7. **Installation Complexity** While easier to remove than fixed covers, proper installation requires alignment with the truck bed s edges. Improper fitting can lead to gaps, reducing effectiveness.

### **Conclusion**

The **RealTruck SL54020 Undercover Select Folding Tonneau Cover** is a practical choice for truck owners who prioritize **convenience, ease of use, and cost-effectiveness** over maximum cargo protection. It excels in scenarios where quick access to the bed is necessary, such as hauling large items or frequently switching between covered and uncovered use. The folding design avoids the hassle of storing a bulky cover separately, and its weather resistance is sufficient for light to moderate conditions.

However, if **maximum security, theft deterrence, or heavy weather protection** are top priorities, a fixed or roll-up tonneau cover might be a better investment. The SL54020 is best suited for **casual users, weekend warriors, or those who need a balance between functionality and simplicity**.

---

- You frequently need full access to your truck bed.

- You want a cover that s easy to install, remove, and store.

- You re looking for an affordable option that provides decent weather protection.

**Consider alternatives (e.g., fixed or roll-up covers) if:**

- You need **maximum protection** from rain, snow, or theft.

- You frequently drive in **harsh weather conditions**.

- You want **motorized or spring-assisted** operation for ease of use.

For most everyday drivers who don t require extreme protection, the SL54020 offers a **good balance of usability and value**. However, always check user reviews and ensure it fits your specific truck bed dimensions before purchasing.
