Safe and Efficient Ways to Power Your Truck Camper Shell
When looking for ways to power your truck camper shell without running wires between the cab and the shell, it can be tempting to utilize the tail-light circuit. However, there are several practical and safe methods you can employ to ensure your camper is powered efficiently and safely. This guide will explore the limitations of using the tail-light circuit and provide alternative solutions that are both effective and safe.
Limitations of Using the Tail-Light Circuit
The tail-light circuit is a popular choice for powering accessories in a truck camper because it potentially doesn’t require the ignition to be on. Unfortunately, the reality is that the tail-light circuit is not designed for such use. It can only provide a few amps at most when the lights are on, making it unsuitable for significant power draws. Additionally, running even a light load can result in blown fuses or damaged wiring. Attempting to exceed its capacity by using a larger fuse can lead to dangerous situations, as the wires are not designed to handle additional current.
Alternatives to the Tail-Light Circuit
For a safer and more reliable power source, consider these alternative options:
1. Camper Plug Fitted in the Trailer Socket
If your truck is equipped with a camper plug in the trailer socket, you can connect your power outlets and appliances directly to the trailer. This method not only eliminates the need for additional wiring but also ensures that you are drawing power from a circuit designed to handle significant loads. Most trailer sockets come with a 30-amp or 50-amp circuit breakers, providing ample power for your needs.
2. Search for Non-Critical Circuits
Many modern trucks offer non-critical circuits that are hot (powered) at all times. These circuits, such as those that power the dome light or dashboard accessory outlets, can be tapped into for power. To determine which circuit is suitable, consult your truck’s manual or an electrical diagram. Alternatively, you may need to install a separate circuit that is dedicated to your camper needs. For optimal safety and performance, always have a qualified electrician handle this task.
3. Running a Line to the Battery
A straightforward solution is to run a direct line from the truck’s battery to the camper. This method ensures a constant and reliable power supply. For older trucks, running wires under the chassis can be a viable option. With modern trucks, manufacturers often provide specific connectors and wiring harnesses for this purpose. Search online for your specific truck model to find detailed instructions and compatible connectors.
Conclusion
While the tail-light circuit might seem like a convenient option for powering your truck camper shell, it is not designed for such usage and comes with significant drawbacks. Safe and efficient power solutions include using a camper plug, tapping into non-critical circuits, or installing a dedicated wiring line directly from the truck’s battery. For the best results, consult with an experienced electrician to ensure your setup is both safe and functional.
