Why I Chose a Diode for Flat Towing Behind My RV

As a frequent traveler, I have always loved the convenience and freedom that comes with owning an RV. However, when it came to towing my car behind my RV, I quickly realized the importance of having a diode installed.

A diode is a small electrical component that allows current to flow in one direction while blocking it in the opposite direction. This makes it an essential addition for flat towing behind an RV as it prevents any backflow of power from the RV to the towed vehicle. Without a diode, the car’s electrical system can become damaged due to the RV’s higher voltage.

Moreover, using a diode also ensures that all of my car’s lights, including brake lights and turn signals, are properly functioning while being towed. This is crucial for safety on the road as other drivers can easily see my intentions while driving and braking.

Additionally, installing a diode for flat towing behind my RV has saved me from the hassle of constantly connecting and disconnecting wires every time I want to tow my car. The diode remains permanently attached to both vehicles, making it convenient and time-saving.

Overall, investing in a diode has not only protected my

My Buying Guide on ‘Diode For Flat Towing Behind Rv’

Introduction

I have been RVing for several years now and one of the most important accessories I have invested in is a diode for flat towing behind my RV. It is a small but essential component that allows you to safely and legally tow your vehicle behind your RV. In this buying guide, I will share my first-hand experience and provide some tips on how to choose the right diode for flat towing behind your RV.

What is a Diode for Flat Towing?

A diode for flat towing is a small electrical device that allows you to safely tow a vehicle behind an RV without causing any damage to its electrical system. It works by isolating the wiring of the towed vehicle from the wiring of the RV, preventing any backflow of electricity that can cause damage to either vehicle.

Why Do You Need a Diode for Flat Towing Behind Your RV?

Without a diode, you risk damaging the electrical system of your towed vehicle or even your RV. The backflow of electricity can cause problems such as blown fuses, short circuits, or even draining the battery of your towed vehicle. A diode ensures that both vehicles are protected and prevents any potential damage.

What to Consider When Buying a Diode for Flat Towing

When looking for a diode for flat towing behind your RV, there are several factors you should consider:

1. Compatibility: Make sure the diode you choose is compatible with both your RV and towed vehicle. Some diodes are designed specifically for certain types of vehicles, so it’s important to check before making a purchase.

2. Quality: Invest in a high-quality diode from a reputable brand. Cheap or poorly made diodes may not be as reliable and could cause problems down the road.

3. Wiring Harness: Some diodes come with their own wiring harness while others require additional wiring harnesses. Make sure you know which one you need before purchasing.

4. Ease of Installation: Look for a diode that is easy to install and does not require any special tools or technical knowledge. This will save you time and frustration during the installation process.

5. Warranty: A good warranty is always a plus when it comes to purchasing any product. Look for diodes that come with at least a one-year warranty.

My Recommendation

After trying out different brands and types of diodes, I highly recommend using Roadmaster’s Universal Hy-Power Diode Wiring Kit. It is compatible with most vehicles, easy to install, and comes with clear instructions. The kit also includes all necessary components such as fuses and connectors, making it convenient and hassle-free.

Conclusion

A diode for flat towing may seem like a small purchase, but it plays an important role in ensuring safe and damage-free towing behind your RV. By considering factors such as compatibility, quality, ease of installation, warranty, and my recommendation above, you can choose the right diode for your needs and have peace of mind during your travels.
