Installing scissor jacks on your travel trailer provides enhanced stability and leveling capabilities, significantly improving your camping experience. This process involves selecting the correct jacks, preparing the trailer frame, securely mounting the jacks, and testing for proper operation. This guide will walk you through each step with clear instructions, ensuring a safe and effective installation.
Preparing for Installation: Selection and Safety
Before you even think about picking up a wrench, careful planning is crucial. Choosing the right scissor jacks and ensuring you have the proper safety equipment will make the installation process smoother and safer.
Choosing the Right Scissor Jacks
Not all scissor jacks are created equal. The weight capacity is the most crucial factor. Always choose jacks rated higher than your trailer’s tongue weight plus the anticipated load in the trailer, with a significant safety margin. Consider the lift height needed for your specific camping locations. Look for jacks made from durable materials like heavy-gauge steel and with a rust-resistant coating. Research reputable brands known for their quality and reliability.
Safety First: Essential Gear and Precautions
Safety should always be your top priority. Before starting any work on your travel trailer, ensure it is parked on a level surface and properly secured with wheel chocks. Disconnect the trailer from your tow vehicle. Wear safety glasses to protect your eyes from debris. Use jack stands to support the trailer frame after lifting it with a floor jack. Work gloves will protect your hands. Understanding the risks involved, such as a collapsing trailer, is paramount; never compromise safety.
The Installation Process: A Step-by-Step Guide
With the proper preparation completed, you can move on to the actual installation of the scissor jacks. This process requires careful attention to detail and adherence to safety guidelines.
1. Identifying Mounting Points
Carefully inspect your travel trailer’s frame to identify suitable mounting locations. These locations should be structurally sound, offering a solid and flat surface for the jack mounting plates. Avoid areas with wiring, plumbing, or other obstructions. The ideal mounting points are usually along the trailer frame rails, near the front and rear axles. Make sure to position the jacks so they won’t interfere with tires or other components when fully extended or retracted.
2. Preparing the Frame for Welding or Bolting
Depending on your chosen method, the frame may need preparation. For welding, clean the area thoroughly with a wire brush to remove any rust, paint, or debris. This ensures a strong and secure weld. For bolting, you may need to drill holes through the frame to accommodate the mounting bolts. Use a drill bit that matches the bolt size, and ensure the holes are clean and deburred. Some frames have pre-drilled holes, which is a huge time-saver.
3. Welding vs. Bolting: Choosing Your Mounting Method
There are two primary methods for attaching scissor jacks: welding and bolting. Welding offers a stronger and more permanent connection, but it requires specialized equipment and skills. If you’re not comfortable welding, consider hiring a professional welder. Bolting is a simpler method that doesn’t require welding equipment, but it’s crucial to use high-quality bolts, washers, and lock nuts to ensure a secure connection. Many kits come with specific bolts, but if not, purchase Grade 8 hardware for maximum strength.
4. Attaching the Scissor Jacks: Welding Procedure (if applicable)
If you choose to weld the scissor jacks to the frame, ensure you have the necessary safety equipment, including a welding helmet, gloves, and appropriate clothing. Position the jack in the desired location and tack weld it in place. Double-check the alignment before completing the weld. Apply multiple passes of weld, ensuring good penetration and a strong bond. Allow the weld to cool completely before applying any weight.
5. Attaching the Scissor Jacks: Bolting Procedure (if applicable)
If you choose to bolt the scissor jacks to the frame, align the jack mounting plate with the pre-drilled or newly drilled holes. Insert the bolts through the mounting plate and the frame, and secure them with washers and lock nuts. Tighten the bolts securely, using a torque wrench to ensure they are tightened to the manufacturer’s specifications. Double-check the tightness of the bolts after a few uses.
6. Testing and Adjusting: Ensuring Proper Function
After installing the scissor jacks, it’s crucial to test them thoroughly. Use a floor jack to lift the trailer slightly and then extend the scissor jacks until they make contact with the ground. Slowly lower the floor jack and observe how the scissor jacks support the weight of the trailer. Ensure the jacks are stable and don’t wobble or flex excessively. Adjust the jacks as needed to achieve a level and stable platform. Check for any binding or unusual noises during operation.
Finishing Touches: Protection and Maintenance
Once the jacks are installed and tested, a few finishing touches will protect your investment and ensure years of reliable service.
Applying Protective Coatings
To prevent rust and corrosion, apply a protective coating to the scissor jacks and the surrounding frame area. Use a rust-resistant primer followed by a durable paint or sealant. Regularly inspect the jacks for any signs of damage or wear.
Regular Maintenance and Inspection
Regular maintenance is essential to prolong the life of your scissor jacks. Lubricate the moving parts with a silicone-based lubricant or white lithium grease. Inspect the jacks for any signs of damage, such as bent frames, worn threads, or loose bolts. Replace any damaged or worn parts immediately.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about installing scissor jacks on travel trailers:
FAQ 1: What is the correct weight rating for scissor jacks on my travel trailer?
The weight rating should exceed your trailer’s tongue weight plus the estimated load inside, with a safety factor of at least 25%. Consult your trailer’s documentation or weigh it at a truck scale for accurate figures.
FAQ 2: Can I install scissor jacks myself, or should I hire a professional?
If you’re comfortable with basic mechanical tasks and understand the safety precautions, you can install scissor jacks yourself. However, if you’re unsure about welding or bolting, it’s best to hire a qualified professional.
FAQ 3: What tools do I need for installing scissor jacks?
Essential tools include: floor jack, jack stands, socket set, wrench set, drill (if bolting), drill bits, wire brush, safety glasses, work gloves, welding equipment (if welding), torque wrench, and measuring tape.
FAQ 4: Where is the best location to mount scissor jacks on my travel trailer frame?
The best location is along the frame rails, near the axles, avoiding any obstructions like wiring or plumbing. Choose flat, structurally sound areas for secure mounting.
FAQ 5: What type of bolts should I use if bolting the scissor jacks to the frame?
Use Grade 8 bolts, washers, and lock nuts for maximum strength and security. Ensure the bolt size matches the mounting holes on the jack and the frame.
FAQ 6: How do I ensure the scissor jacks are level during installation?
Use a level to ensure the mounting plates are aligned horizontally and vertically before welding or bolting. Adjust as needed to achieve a level installation.
FAQ 7: What type of welding process is recommended for attaching scissor jacks?
MIG welding is generally recommended for its ease of use and good penetration. However, stick welding or TIG welding can also be used by experienced welders.
FAQ 8: How often should I lubricate the scissor jacks?
Lubricate the scissor jacks at least twice a year, or more frequently if you camp often in dusty or wet conditions. Use a silicone-based lubricant or white lithium grease.
FAQ 9: What are the signs that my scissor jacks need to be replaced?
Signs of wear include bent frames, stripped threads, excessive rust, or difficulty extending or retracting the jacks.
FAQ 10: Can I use scissor jacks to lift the entire travel trailer for tire changes?
Scissor jacks are primarily designed for stabilization and leveling, not for lifting the entire trailer. Use a dedicated floor jack or bottle jack for tire changes.
FAQ 11: Will installing scissor jacks void my travel trailer’s warranty?
It depends on the manufacturer and the terms of the warranty. Check your warranty documentation or contact the manufacturer for clarification. Generally, alterations can void warranties if deemed the cause of damage.
FAQ 12: How do I properly store scissor jacks when not in use?
Clean the scissor jacks thoroughly and apply a protective coating. Store them in a dry, protected location to prevent rust and damage. Retract them fully for storage.
