Jacking a travel trailer, whether for maintenance, tire changes, or leveling, requires careful planning and execution to ensure safety and prevent damage. The core principle revolves around selecting appropriate jacking points, utilizing the correct equipment, and following a systematic procedure to lift and support the trailer securely.
Understanding the Importance of Proper Jacking Techniques
Incorrect jacking practices can lead to serious consequences, including damage to the trailer’s frame, suspension components, or even personal injury. A travel trailer’s construction, with its comparatively thin skin and welded frame, is not designed to withstand stresses applied in arbitrary locations. That’s why understanding the specific jacking points designated by the manufacturer and using the right type of jack are crucial. This guide, drawing on years of experience and industry best practices, will equip you with the knowledge and skills to confidently and safely jack your travel trailer.
Preparing for the Jacking Process
Before you even touch a jack, a comprehensive preparation phase is essential. This involves assessing the situation, gathering the necessary tools, and implementing crucial safety measures.
Assessing the Situation
Begin by evaluating the ground surface. It must be firm and level. Soft ground can cause the jack to sink, leading to instability. Use leveling blocks or sturdy wooden planks to create a stable base for the jack. Consider the reason for jacking. Is it for a tire change, maintenance, or leveling? This will influence the jacking point and the height required.
Gathering the Right Tools
You’ll need the following:
- Appropriate Jack: Bottle jack, scissor jack, or hydraulic jack specifically rated for your trailer’s weight.
- Safety Stands: Never work under a trailer supported only by a jack. Safety stands are non-negotiable.
- Wheel Chocks: Prevent accidental rolling by securing the wheels on the opposite side of the trailer.
- Wrench or Socket Set: To loosen lug nuts if you’re changing a tire.
- Gloves: Protect your hands.
- Leveling Blocks (Optional): For fine-tuning leveling adjustments.
- Owner’s Manual: Your trailer’s manual is the ultimate authority on recommended jacking points.
Implementing Safety Measures
Safety is paramount. Before starting, engage the parking brake, chock the wheels opposite the jacking point, and ensure the area is clear of people and pets. Never, under any circumstances, work under a trailer supported solely by a jack. Always use safety stands.
Identifying Correct Jacking Points
Locating the correct jacking points is arguably the most critical step. Incorrect placement can cause severe damage to the trailer’s frame or body.
Consulting the Owner’s Manual
The owner’s manual is your first and most reliable source of information. It will specify the designated jacking points for your particular trailer model.
Identifying Frame Rails
If the owner’s manual is unavailable, generally, the strongest points are directly on the frame rails. These are the longitudinal steel beams that run the length of the trailer. Look for reinforced areas, often near axles or suspension mounting points. Avoid jacking directly on the trailer’s floor or any lightweight structural components.
Utilizing Axle U-Bolts (With Caution)
In some cases, jacking under the U-bolts that secure the axle to the leaf springs is acceptable, but only if explicitly recommended by the manufacturer or if the U-bolts are specifically designed for jacking. Using the U-bolts without confirmation can damage the axle or U-bolts themselves.
Executing the Jacking Procedure
With the preparation complete and the jacking points identified, you can proceed with the jacking process.
Positioning the Jack
Carefully position the jack under the selected jacking point. Ensure it is stable and centered. Use a wooden block or rubber pad between the jack and the frame to protect the frame’s finish and distribute the load evenly.
Raising the Trailer
Slowly and steadily raise the trailer, monitoring the jacking point for any signs of stress or bending. If you notice anything unusual, stop immediately and reassess the situation.
Supporting the Trailer with Safety Stands
Once the trailer is raised to the desired height, immediately position the safety stands under the frame rails, as close to the jacking point as possible. Never place safety stands under the axle. Adjust the stands to ensure they are securely supporting the trailer’s weight before removing the jack.
Lowering the Trailer
Slowly lower the trailer onto the safety stands. Double-check that the stands are firmly supporting the weight before removing the jack completely.
Lowering the Trailer After Maintenance
After completing your work, slowly raise the trailer slightly to remove the safety stands. Carefully lower the trailer back to the ground. Ensure the jack is stable and controlled throughout the lowering process.
Frequently Asked Questions (FAQs)
Here are some common questions and answers regarding jacking travel trailers:
FAQ 1: What type of jack is best for a travel trailer?
The best type depends on the trailer’s weight and your personal preference. Bottle jacks offer high lifting capacity and compact size. Scissor jacks are often included with trailers but can be slower and less stable. Hydraulic jacks provide smooth and controlled lifting but are typically more expensive. Always choose a jack rated for more than the trailer’s weight.
FAQ 2: Can I use a car jack to lift my travel trailer?
Generally, no. Car jacks are often not rated for the weight of a travel trailer and may not have sufficient lift height. Using a car jack is unsafe and could damage your trailer.
FAQ 3: How high should I lift my travel trailer?
Lift only as high as necessary to perform the required task. Lifting higher than needed increases the risk of instability. For tire changes, just enough clearance to remove the wheel is sufficient.
FAQ 4: What if I can’t find the designated jacking points?
Consult your owner’s manual. If unavailable, contact the trailer manufacturer or a qualified RV technician. Guessing can lead to costly damage.
FAQ 5: What if the ground is soft?
Use large, solid leveling blocks or wooden planks to distribute the weight of the jack and prevent it from sinking into the ground.
FAQ 6: Can I use a jack to level my travel trailer?
While a jack can be used for minor leveling adjustments, it’s not the primary tool for leveling. Use leveling blocks under the tires for this purpose. The jack is better suited for individual wheel lifting.
FAQ 7: How do I prevent the trailer from rolling when I’m jacking it up?
Engage the parking brake and chock the wheels on the opposite side of the trailer from the jacking point. Double-check that the chocks are securely in place.
FAQ 8: What if my trailer doesn’t have a frame rail?
Some smaller trailers might have a unibody construction. In these cases, the owner’s manual is essential for identifying reinforced jacking points.
FAQ 9: How often should I inspect my jack for damage?
Inspect your jack before each use for signs of leaks, cracks, or other damage. Replace the jack if it’s compromised.
FAQ 10: Can I weld my own jacking points onto the frame?
Welding onto the frame can compromise its structural integrity. Consult a qualified RV technician or frame specialist before making any modifications.
FAQ 11: What should I do if the trailer slips off the jack?
Stop immediately! Do not attempt to catch the trailer. Carefully assess the situation and use a different jack or a more stable jacking point to safely re-lift the trailer.
FAQ 12: Where can I find a qualified RV technician if I’m uncomfortable jacking my trailer myself?
Search online for “RV repair near me” or contact local RV dealerships for recommendations. A qualified technician can safely and properly jack your trailer and perform any necessary repairs.
By following these guidelines and prioritizing safety, you can confidently and effectively jack your travel trailer, ensuring a smooth and secure experience. Remember, when in doubt, consult the owner’s manual or seek professional assistance.
