We're going to break down exactly what it includes, why it matters, and how it can make your towing experience a whole lot smoother. So, buckle up and let’s get started!

What is the 2020 GMC Sierra Trailering Package?

The trailering package for the 2020 GMC Sierra is essentially a set of equipment and features designed to enhance the truck's towing capabilities. It's not just a single component, but rather a combination of several important elements working together. The main goal? To make towing safer, easier, and more efficient. Think of it as the ultimate upgrade for anyone who needs their Sierra to pull its weight – literally!

The key here is understanding that this package isn't just about adding a hitch. It involves optimizing various aspects of the truck to handle the stresses and demands of towing. This includes improving the cooling system, enhancing the electrical connections, and providing features that aid in controlling the trailer. When properly equipped with the trailering package, your 2020 GMC Sierra becomes a towing beast, ready to tackle a wide range of hauling tasks.

For instance, let's say you're planning a weekend getaway with a travel trailer. Without the trailering package, your Sierra might struggle with the added weight, leading to overheating, reduced braking performance, and a generally stressful driving experience. However, with the trailering package, you'll have the confidence of knowing that your truck is properly equipped to handle the load, making your trip safer and more enjoyable. Whether it's boats, campers, or work equipment, the trailering package is designed to give you peace of mind when you're on the road.

Key Components of the Trailering Package

Okay, so what exactly comes inside the 2020 GMC Sierra trailering package? Let's break it down piece by piece so you know what you’re getting.

1. Trailer Hitch Receiver

At the heart of the trailering package is the trailer hitch receiver. This is the crucial connection point between your truck and the trailer. The receiver is a sturdy, frame-mounted component designed to accept various types of trailer hitches. It ensures a secure and reliable connection, giving you the confidence that your trailer is safely attached to your Sierra.

The receiver is typically rated for a specific weight capacity, so it's essential to choose the right one for your towing needs. The 2020 GMC Sierra's trailering package usually includes a heavy-duty receiver that can handle a significant amount of weight. Always check the weight ratings to ensure you're within the safe limits for your truck and trailer.

2. Trailer Wiring Harness

Next up is the trailer wiring harness. This is what provides the electrical connection between your Sierra and the trailer. It allows you to control the trailer's lights, including brake lights, turn signals, and running lights. Without a properly functioning wiring harness, your trailer won't be visible to other drivers, creating a major safety hazard.

The 2020 GMC Sierra's trailering package includes a 7-pin wiring harness connector, which is the industry standard for most trailers. This connector provides all the necessary electrical connections for lights and brakes. It's also weather-resistant, ensuring a reliable connection even in harsh conditions. Before each trip, make sure to inspect the wiring harness for any damage or corrosion.

3. Enhanced Cooling System

Towing heavy loads puts a lot of strain on your truck's engine and transmission. To prevent overheating, the trailering package includes an enhanced cooling system. This typically consists of a larger radiator and an auxiliary transmission oil cooler.

The larger radiator provides increased cooling capacity, helping to keep your engine running at a safe temperature, even when towing uphill or in hot weather. The auxiliary transmission oil cooler helps to dissipate heat generated by the transmission, preventing it from overheating and potentially failing. Overheating can cause serious damage to your engine and transmission, so this is a crucial component of the trailering package.

4. Trailer Brake Controller

For heavier trailers, a trailer brake controller is essential. This device allows you to control the trailer's brakes independently from the truck's brakes. It provides smoother and more controlled stopping power, especially when towing heavy loads. The 2020 GMC Sierra's trailering package often includes a pre-wired connection for a trailer brake controller, making it easy to install an aftermarket unit.

A trailer brake controller works by sensing when you apply the brakes in your truck and then applying the brakes on the trailer proportionally. This helps to prevent the trailer from pushing against the truck, which can cause instability and loss of control. Properly adjusting the trailer brake controller is crucial for safe and effective braking.

5. Tow/Haul Mode

The Tow/Haul mode is a special setting that optimizes your truck's performance for towing. When activated, it changes the transmission's shift points, holding gears longer and providing more power when needed. It also helps to reduce the amount of shifting, which can generate heat and wear on the transmission. The Tow/Haul mode is easily activated with the push of a button and can make a significant difference in your towing experience.

By holding gears longer, the Tow/Haul mode keeps your engine in its optimal power range, providing the torque you need to pull heavy loads. It also helps to prevent the transmission from constantly shifting up and down, which can be annoying and inefficient. Always use the Tow/Haul mode when towing to get the best performance and fuel economy.

Why is the Trailering Package Important?

So, why should you even bother with the trailering package? Well, for starters, it's all about safety. Towing without the proper equipment can be incredibly dangerous. The trailering package ensures that your truck is properly equipped to handle the added weight and stress of towing, reducing the risk of accidents.

Beyond safety, the trailering package also enhances performance. With the enhanced cooling system and Tow/Haul mode, your truck will be able to tow more efficiently and effectively. You'll experience better acceleration, braking, and overall control, making your towing experience much more enjoyable.

Finally, the trailering package can protect your investment. Towing without the proper equipment can put undue stress on your truck's engine, transmission, and brakes, leading to premature wear and tear. The trailering package helps to mitigate these risks, extending the life of your truck and saving you money on repairs in the long run.

Is the Trailering Package Right for You?

Now, the big question: Is the trailering package the right choice for you and your 2020 GMC Sierra? The answer really boils down to how you plan to use your truck. If you're only occasionally towing light loads, like a small utility trailer, you might be able to get away without the full trailering package. However, if you're planning to tow heavier loads on a regular basis, the trailering package is definitely worth the investment.

Consider the types of trailers you'll be towing, the weight of those trailers, and the conditions in which you'll be towing. If you're planning to tow a travel trailer, boat, or heavy equipment, the trailering package is a must-have. It will give you the confidence and peace of mind knowing that your truck is properly equipped to handle the task. Even if you only tow occasionally, the added safety and performance benefits of the trailering package can be well worth the cost.

Final Thoughts

The 2020 GMC Sierra trailering package is a fantastic addition for anyone who needs to tow. It provides the necessary equipment and features to make towing safer, easier, and more efficient. From the trailer hitch receiver to the enhanced cooling system, each component is designed to work together to optimize your truck's towing capabilities.

So, if you're in the market for a 2020 GMC Sierra and you plan to do any towing, be sure to opt for the trailering package. It's an investment that will pay off in the long run, providing you with years of reliable and safe towing performance. Happy hauling!
