Upgrading your travel trailer with an electric jack significantly simplifies the often-tedious task of hitching and unhitching. By replacing your manual crank jack, you’ll enjoy effortless leveling and increased convenience at the campsite. This guide provides a detailed, step-by-step process, along with essential tips and considerations, for a successful electric jack installation.
Assessing Your Needs and Choosing the Right Jack
Before diving into the installation process, it’s crucial to select the right electric jack for your travel trailer. Key factors to consider include:
- Weight Capacity: The jack’s weight capacity must exceed the tongue weight of your trailer. Refer to your trailer’s specifications or use a tongue weight scale to accurately determine this. Overestimating is always safer than underestimating.
- Lifting Height: Ensure the jack provides sufficient lifting height to accommodate your hitch ball and any variations in ground level.
- Mounting Style: Most electric jacks are A-frame jacks, designed to fit standard A-frame couplers. Verify compatibility with your trailer’s existing setup.
- Power Requirements: Electric jacks typically operate on 12-volt DC power. Confirm your trailer’s electrical system can handle the additional load.
- Features: Consider features like a built-in light, remote control operation, or an emergency crank handle for manual operation if the power fails.
Gathering Necessary Tools and Materials
Proper preparation is key to a smooth installation. Gather the following tools and materials before you begin:
- Electric Jack: The selected electric jack with included mounting hardware.
- Wrenches and Sockets: A set of wrenches and sockets to fit the existing jack’s mounting bolts and the new jack’s hardware.
- Screwdrivers: Phillips head and flathead screwdrivers.
- Wire Strippers/Crimpers: For connecting the jack to the electrical system.
- Electrical Connectors: Butt connectors or ring terminals for secure wiring connections.
- Electrical Tape: To insulate and protect wiring connections.
- Multimeter: To verify voltage and ground connections.
- Drill (Optional): May be needed for new mounting holes or wiring access.
- Safety Glasses and Gloves: For personal protection.
- Wheel Chocks: To secure the trailer during the installation process.
- Jack Stands: For added safety while working under the trailer.
- Battery Charger (Optional): To ensure a fully charged battery.
Step-by-Step Installation Guide
Follow these steps carefully to ensure a safe and successful electric jack installation:
1. Safety First: Prepare the Trailer
- Park the trailer on a level surface.
- Engage the parking brake and chock the wheels to prevent movement.
- Disconnect the trailer from the tow vehicle.
- Use jack stands to support the trailer frame for added safety.
2. Remove the Old Manual Jack
- Lower the manual jack to its lowest position.
- Disconnect any wiring connected to the existing jack (if applicable).
- Using the appropriate wrenches or sockets, remove the bolts securing the manual jack to the trailer frame.
- Carefully lift the old jack off the trailer frame.
3. Prepare the Mounting Surface
- Clean the mounting surface on the trailer frame to remove any rust, dirt, or debris.
- Inspect the frame for any damage or corrosion. Repair as needed before proceeding.
- If necessary, drill new mounting holes to align with the electric jack’s mounting plate. Use a drill bit appropriate for the frame material.
4. Install the Electric Jack
- Position the electric jack on the mounting surface, aligning the mounting holes.
- Secure the jack with the provided mounting hardware. Tighten the bolts according to the manufacturer’s instructions. Over-tightening can damage the frame or the jack.
- Ensure the jack is securely mounted and does not wobble or move.
5. Wire the Electric Jack
- Locate the power and ground wires on the electric jack. Refer to the manufacturer’s wiring diagram.
- Connect the power wire to the positive (+) terminal on the trailer battery. Use a fused connection (usually an inline fuse near the battery) for protection.
- Connect the ground wire to a clean, unpainted metal surface on the trailer frame. This provides a solid ground connection.
- Use electrical connectors (butt connectors or ring terminals) to ensure secure and weatherproof connections.
- Wrap all connections with electrical tape for added insulation and protection.
- Use a multimeter to verify voltage and ground connections.
6. Test the Electric Jack
- Ensure the trailer battery is fully charged.
- Activate the electric jack using the control switch or remote.
- Raise and lower the jack to its full range of motion.
- Check for any binding, unusual noises, or electrical issues.
- Verify the built-in light (if equipped) is functioning properly.
7. Final Inspection and Clean Up
- Double-check all connections and mounting hardware to ensure they are secure.
- Route the wiring neatly and secure it to the trailer frame to prevent damage.
- Remove the jack stands and lower the trailer.
- Clean up any tools or debris from the work area.
Troubleshooting Common Issues
- Jack not working: Check the fuse, battery voltage, and wiring connections.
- Jack is slow or weak: Ensure the battery is fully charged and the tongue weight is within the jack’s capacity.
- Jack makes unusual noises: Inspect the jack for damage or obstructions. Lubricate moving parts if necessary.
Frequently Asked Questions (FAQs)
FAQ 1: What size fuse should I use for my electric jack?
The appropriate fuse size depends on the amperage draw of your electric jack. Consult the manufacturer’s specifications for the recommended fuse size. A commonly used fuse size is 30 amps, but always verify the requirement for your specific model.
FAQ 2: Can I wire my electric jack directly to the tow vehicle’s battery?
While possible, it’s generally not recommended to wire directly to the tow vehicle’s battery. The travel trailer’s battery is designed to handle the load and provide a stable power source. Connecting to the tow vehicle could drain its battery.
FAQ 3: What is the best way to protect the wiring from the elements?
Use heat shrink tubing over your electrical connections after crimping them. Additionally, route the wiring away from areas prone to water spray or damage. Consider using conduit to protect the wiring along the trailer frame.
FAQ 4: How often should I lubricate my electric jack?
Lubricate the jack’s screw mechanism every 3-6 months, or more frequently if you use it heavily or in harsh conditions. Use a lithium-based grease specifically designed for RV components.
FAQ 5: Can I use an electric jack on a gooseneck trailer?
Electric jacks are typically designed for A-frame trailers. While modifications might be possible, it’s best to consult with a trailer specialist for suitable lifting solutions for gooseneck trailers.
FAQ 6: What do I do if my electric jack stops working while the trailer is hitched?
If the electric jack fails, use the emergency crank handle (if provided) to manually raise or lower the jack. Alternatively, you may need to use a bottle jack placed under the trailer frame to lift the trailer off the hitch.
FAQ 7: How do I know if my trailer battery is strong enough for an electric jack?
A fully charged 12-volt deep-cycle battery is generally sufficient. However, if you experience slow operation or frequent battery drain, consider upgrading to a larger capacity battery or adding a second battery.
FAQ 8: Can I install an electric jack myself, or should I hire a professional?
While DIY installation is possible with basic mechanical and electrical skills, if you are uncomfortable working with electrical systems or lifting heavy objects, it’s best to hire a qualified RV technician.
FAQ 9: What is the typical lifespan of an electric jack?
With proper maintenance and care, an electric jack can last for 5-10 years or longer. Factors affecting lifespan include usage frequency, environmental conditions, and adherence to the manufacturer’s recommendations.
FAQ 10: Are all electric jacks waterproof?
No, not all electric jacks are fully waterproof. Look for jacks with a weather-resistant or waterproof rating if you frequently camp in wet conditions.
FAQ 11: What are the benefits of an electric jack with a remote control?
A remote control allows you to operate the jack from a distance, making it easier to level the trailer while observing it from different angles. This is particularly helpful when hitching or unhitching in tight spaces.
FAQ 12: How much weight can an electric jack lift?
Electric jacks are available with weight capacities ranging from 2,000 lbs to 5,000 lbs or more. Choose a jack that exceeds your trailer’s tongue weight by a comfortable margin.
By carefully following these steps and considering the FAQs, you can successfully install an electric jack on your travel trailer and enjoy the added convenience and ease of use for years to come.
