Jacking up a travel trailer is essential for tasks ranging from tire changes and bearing maintenance to seasonal storage and leveling on uneven ground. The process, while seemingly straightforward, demands precision and adherence to safety protocols to prevent accidents and damage to your valuable investment. This guide offers a detailed, step-by-step approach to jacking up your travel trailer safely and efficiently, ensuring a smooth experience for both seasoned RVers and newcomers alike.
Understanding the Fundamentals
Before delving into the mechanics, understanding the basic principles and necessary equipment is crucial. Improper jacking techniques can lead to instability, causing the trailer to shift, potentially resulting in serious injury or property damage. The primary goal is to create a stable lifting point that distributes the weight evenly and minimizes the risk of slippage.
Essential Equipment
- Heavy-Duty Jack: Crucially, use a jack rated for at least half the weight of your trailer’s gross vehicle weight rating (GVWR). Bottle jacks and scissor jacks are common, but bottle jacks generally offer more lifting power.
- Jack Stands: Never, ever work under a trailer supported only by a jack. Always use jack stands, also rated for at least half the trailer’s GVWR, as the primary support.
- Wheel Chocks: These are vital for preventing movement of the trailer during the jacking process. Use two chocks per wheel.
- Lug Wrench: If you’re jacking up the trailer to change a tire, a lug wrench is necessary.
- Torque Wrench: Essential for properly tightening lug nuts after a tire change. Over-tightening or under-tightening can lead to serious problems.
- Gloves: Protect your hands from dirt, grease, and sharp edges.
- Safety Glasses: Protect your eyes from debris.
- Level: Helpful for ensuring the trailer is level after jacking.
- Wood Blocks or Jack Pads: These provide a stable base for the jack, especially on soft ground.
Step-by-Step Guide to Jacking Up Your Travel Trailer
Following these steps meticulously will ensure a safe and successful jacking process.
1. Preparation is Key
- Choose a Level Surface: Select a level, solid surface to minimize the risk of instability. Avoid soft ground, such as sand or mud, unless you have adequate support (like wood blocks) for the jack and stands.
- Engage Parking Brake: Ensure the trailer’s parking brake is fully engaged.
- Chock the Wheels: Position wheel chocks snugly behind and in front of the wheels that will remain on the ground.
- Gather Your Tools: Have all necessary equipment within easy reach.
2. Locating the Jacking Points
- Consult Your Owner’s Manual: The trailer’s owner’s manual is the definitive source for identifying the designated jacking points. These are typically reinforced areas of the frame specifically designed to withstand the weight of the trailer.
- Frame Rails: In many cases, the frame rails located near the axles are suitable jacking points.
- Avoid Axles: Never jack directly on the axles themselves. This can cause damage to the axle components and potentially compromise the structural integrity of the axle.
3. Positioning the Jack
- Place the Jack: Position the jack directly under the designated jacking point. Ensure the jack is stable and firmly seated on its base. Use wood blocks or jack pads if necessary to provide a solid foundation.
- Slowly Raise the Jack: Slowly and steadily raise the jack until it makes contact with the jacking point. Double-check that the jack is properly aligned and secure.
4. Lifting the Trailer
- Raise the Trailer Gradually: Gradually raise the trailer to the desired height. Avoid jerky movements, as this can destabilize the trailer.
- Monitor Stability: Continuously monitor the stability of the trailer as you raise it. If you notice any signs of instability, such as rocking or tilting, immediately stop and reassess the situation.
5. Positioning the Jack Stands
- Place Jack Stands: Once the trailer is raised to the desired height, carefully position jack stands under the frame rails, near the jacking point. Ensure the jack stands are also resting on a solid and level surface.
- Lower the Trailer Onto the Stands: Slowly lower the trailer onto the jack stands. Make sure the stands are supporting the weight of the trailer before removing the jack.
6. Final Checks and Lowering
- Verify Stability: Before working under the trailer, thoroughly verify that it is stable and securely supported by the jack stands. Give the trailer a gentle nudge to ensure it is not going to shift.
- Reverse the Process: To lower the trailer, slightly raise it with the jack, remove the jack stands, and then slowly lower the trailer back to the ground.
Frequently Asked Questions (FAQs)
1. What type of jack is best for jacking up a travel trailer?
The best type of jack depends on the size and weight of your trailer. Bottle jacks are powerful and suitable for larger trailers, while scissor jacks are more compact and often sufficient for smaller trailers. Always ensure the jack is rated for at least half your trailer’s GVWR.
2. Can I jack up my travel trailer on soft ground?
Jacking a trailer on soft ground is risky but possible with proper precautions. Use large, solid wood blocks or jack pads under the jack and jack stands to distribute the weight and prevent them from sinking into the ground. Regularly check for sinking and adjust as needed.
3. Where are the correct jacking points on my travel trailer?
Consult your owner’s manual for the definitive locations of the jacking points. These are typically reinforced sections of the frame, usually near the axles. Never jack directly on the axles themselves.
4. How high should I jack up my travel trailer?
Jack the trailer high enough to accomplish the task at hand, such as changing a tire or lubricating bearings. Avoid raising it unnecessarily high, as this increases the risk of instability. For tire changes, just enough clearance for the inflated tire is sufficient.
5. Is it safe to work under a travel trailer supported only by a jack?
Absolutely not. Never, ever work under a trailer supported only by a jack. Always use jack stands as the primary support and ensure they are properly rated for the weight of the trailer.
6. How do I know if my travel trailer is level after jacking it up?
Use a level placed on a stable surface inside the trailer, such as a countertop or the floor. Adjust the jack stands as needed to achieve a level position.
7. What should I do if the trailer starts to wobble while I’m jacking it up?
Immediately stop jacking and reassess the situation. Lower the trailer slightly, check the jack’s positioning and stability, and ensure the ground is solid. If necessary, reposition the jack or add support under the base.
8. How often should I check the lug nuts after changing a tire?
After changing a tire, check the lug nuts after driving approximately 50-100 miles. Use a torque wrench to ensure they are tightened to the manufacturer’s specified torque.
9. Can I use a car jack to lift my travel trailer?
While a car jack might work in an emergency, it is generally not recommended. Car jacks are typically not rated for the weight of a travel trailer and may be unstable. Using a jack specifically designed for trailers is always the safest option.
10. What is the GVWR of my travel trailer and why is it important?
GVWR stands for Gross Vehicle Weight Rating. It’s the maximum permissible weight of the trailer, including all cargo, fluids, and passengers (if applicable). Knowing your GVWR is essential for selecting appropriately rated jacks and jack stands. This information is typically found on a sticker near the trailer’s entrance or in the owner’s manual.
11. Do I need to disconnect the battery or propane tanks before jacking up my travel trailer?
Disconnecting the battery is generally not necessary unless you are working on electrical components. However, it’s a good practice. You do not need to disconnect the propane tanks, but ensure they are securely fastened.
12. What are the signs that I need to replace my travel trailer tires?
Look for signs of wear and tear, such as cracks in the sidewall, bulges, uneven wear, or tread depth below the legal limit. Also, consider the tire’s age; even if they look good, tires should be replaced after five to seven years, regardless of mileage, due to rubber degradation. Refer to the DOT number on the tire sidewall to determine its manufacturing date.
