Why You Might Need to Jack Up Your Motorhome

There are several reasons why a motorhome owner might need to lift their vehicle. Common scenarios include:

• Tire Changes: If you get a flat tire, you’ll need to lift the corner of the motorhome to remove and replace it.
• Brake or Suspension Work: Accessing components like brake pads, rotors, or suspension parts often requires lifting the vehicle.
• Underbody Inspections: Checking for leaks, damage, or rust underneath the motorhome is easier when it’s elevated.
• Wheel Bearing Maintenance: Lubricating or replacing wheel bearings necessitates lifting the wheel.
• Leveling and Stabilization: While often done with stabilizing jacks at the corners, sometimes a more significant lift is needed for initial motorhome leveling or to place leveling blocks underneath.
• Storage Preparation: Lifting and placing the motorhome on sturdy blocks can reduce stress on tires and suspension during long-term storage.

Essential Safety Precautions Before You Begin

Safety is paramount when working with heavy machinery like a motorhome. Always prioritize these precautions:

• Read Your Owner’s Manual: This is the most crucial step. Your manual will detail specific jacking points and any manufacturer recommendations for lifting your particular model.
• Choose a Level Surface: Never attempt to jack up your motorhome on soft ground, an incline, or uneven terrain. A hard, flat, level surface is essential.
• Engage Parking Brake: Ensure the parking brake is firmly applied.
• Chock the Wheels: Place wheel chocks on the wheels that will remain on the ground, on both the front and back sides of the tires.
• Disconnect from Shore Power and Utilities: Unplug any electrical cords, water hoses, and sewer lines.
• Secure Loose Items: Remove or secure any items inside the motorhome that could shift or fall when the vehicle is lifted.
• Have a Helper: It’s highly recommended to have another person assist you. They can operate the jacks, monitor the lift, and provide an extra layer of safety.

Choosing the Right Equipment for RV Jacking

The type of equipment you use for RV jacking will depend on the task at hand and the weight of your motorhome. Motorhomes are significantly heavier than standard passenger vehicles, so using the correct tools is vital.

Types of Jacks Suitable for Motorhomes

• Hydraulic Jacks: These are powerful and commonly used.
  • Bottle Jacks: Compact and relatively inexpensive, suitable for lifting one corner at a time. Ensure the jack’s weight rating significantly exceeds your motorhome’s corner weight.
  • Floor Jacks: Offer more stability and a wider base. These are often used in professional settings but can be cumbersome for on-the-go repairs.
  • Power Jacks: Some modern motorhomes come with electric or hydraulic jacks built into their leveling systems. Familiarize yourself with their operation.
• Scissor Jacks: While common for cars, larger, heavy-duty scissor jacks can be used for motorhomes, especially for minor adjustments or motorhome leveling. They require more effort to operate but offer good stability.
• Stabilizing Jacks (or Leveling Jacks): These are typically found on the corners of motorhomes and are designed for motorhome leveling and stabilization, not for lifting the entire vehicle off the ground. They are generally not strong enough for tire changes or significant repairs that require lifting a wheel completely.
• Mobile Home Jacks: These are heavy-duty jacks specifically designed for lifting mobile homes, which are often heavier than many motorhomes. They can be a good option if you have a very large and heavy Class A motorhome, but ensure they are rated appropriately for your RV.

Important Considerations for Jack Selection:

• Weight Capacity: This is the most critical factor. Your jack’s rated capacity must be substantially higher than the weight it will be lifting. A motorhome can weigh anywhere from 10,000 to 40,000 pounds or more. A jack rated for 5 tons (10,000 pounds) might be suitable for a small Class C at one corner, but a larger Class A will require much higher capacity jacks, likely in the 10-20 ton range per jack.
• Lift Height: Ensure the jack can lift the vehicle high enough to perform the necessary work, including removing a tire or placing supports.
• Stability: A wider base and a stable design are crucial to prevent the jack from tipping.
• Portability: If you plan to use the jack for roadside repairs, its size and weight will be a consideration.

Essential Support Equipment

• Jack Stands: Absolutely critical for safety. Never work under a motorhome supported only by a jack. Jack stands provide stable support once the vehicle is lifted. Ensure they are also rated for the weight of your motorhome.
• Wood Blocks and Leveling Blocks: Sturdy pieces of wood (like 4x4s or 6x6s) are used to distribute the weight of the jack and the motorhome over a larger area, protecting the frame and the ground. Leveling blocks are also useful for initial positioning and ensuring the jacks are placed on a firm surface.
• Jack Pad Adapters: Some RV frames or specific jacking points might benefit from a rubber or wood adapter to prevent damage to the frame or the jack itself.

Step-by-Step Guide to Jacking Up Your Motorhome

This guide assumes you need to lift one corner of your motorhome, such as for a tire change. The principles apply to lifting other sections, but always consult your owner’s manual for specific jacking points.

Phase 1: Preparation and Positioning

1. Find a Suitable Location: Select a firm, level, and solid surface. An asphalt or concrete surface is ideal. Avoid soft ground, gravel, or grass where jacks or supports could sink.
2. Engage All Safety Measures:
   • Park the motorhome on the chosen level spot.
   • Apply the parking brake firmly.
   • Shift the transmission to Park (automatic) or engage a low gear (manual).
   • Turn off the engine.
   • Place wheel chocks securely on the wheels that will not be lifted. For example, if you’re lifting the front passenger side, chock the front driver side wheel (front and back) and the rear wheels (front and back).
   • Disconnect from any external utilities (shore power, water, sewer).
3. Identify the Correct Jacking Point:
   • Consult your motorhome’s owner’s manual for the designated jacking points. These are typically reinforced sections of the chassis or frame designed to bear the load.
   • Using an incorrect jacking point can cause serious damage to the body, frame, or suspension components.
   • Common jacking points are often near the axles or along the main chassis rails.
4. Prepare the Jacking Area:
   • Place a sturdy piece of wood (e.g., a 6×6 or a few layers of 2x6s) on the ground at the jacking point. This spreads the load and prevents the jack from sinking.
   • If the ground is slightly uneven, use leveling blocks to create a perfectly level and stable base for the wood.

Phase 2: Lifting the Motorhome

1. Position the Jack:
   • Place the jack directly under the identified jacking point, on top of the prepared wood block.
   • Ensure the jack is positioned vertically and squarely under the load.
2. Begin Lifting:
   • Slowly and steadily operate the jack (pump the handle for hydraulic jacks, turn the crank for scissor jacks).
   • As the jack starts to lift the motorhome, watch the contact points closely. Ensure the jack remains centered and the wood block is stable.
   • Have your helper watch the lifting process from a safe distance, communicating any signs of instability.
3. Lift to the Required Height:
   • Lift the motorhome only as high as necessary to complete your task. For a tire change, you need enough clearance to remove the old tire and install the new one.
   • As the weight comes onto the jack, you’ll notice the vehicle lifting. Continue pumping or cranking until you reach the desired height.

Phase 3: Securing the Motorhome with Jack Stands

1. Position Jack Stands:
   • Once the motorhome is at the correct height, place a jack stand on each side of the jack, under the designated jacking points or sturdy frame members.
   • The jack stands should be positioned to support the weight of the motorhome securely.
   • Adjust the height of the jack stands using their locking mechanisms so they are snug against the chassis but not yet bearing the full weight.
2. Lower the Motorhome onto Jack Stands:
   • Very slowly and carefully lower the motorhome by releasing the pressure on the jack.
   • Allow the weight of the motorhome to settle gently onto the jack stands.
   • The jack can be slightly lowered so it’s no longer bearing the primary load, but it’s good practice to leave it in place, lightly touching the chassis, as an additional safety measure.
3. Verify Stability:
   • Gently push and pull on the motorhome to ensure it is stable and securely supported by the jack stands.
   • Check that the jack stands are not shifting or sinking into the ground. If they are, you may need to reposition them on more robust supports.

Phase 4: Performing the Necessary Work

• With the motorhome safely supported, you can now proceed with your tire change, brake repair, or other maintenance.
• Always keep your body parts out from directly underneath the vehicle. Use tools to reach components.

Phase 5: Lowering the Motorhome

1. Prepare to Lower:
   • Gather all tools and parts from under the motorhome.
   • Ensure no one is beneath the vehicle.
2. Lift Slightly:
   • Use the jack to lift the motorhome just enough to take the weight off the jack stands.
3. Remove Jack Stands:
   • Carefully slide the jack stands out from under the motorhome.
4. Slowly Lower:
   • Very slowly and controlledly, lower the motorhome all the way to the ground by releasing the pressure on the jack.
   • Continue to monitor the jack and the vehicle as it descends.
5. Final Checks:
   • Once the motorhome is on the ground, remove the jack and the wood blocks.
   • Remove the wheel chocks.
   • Double-check that all lug nuts (if you changed a tire) are tightened to the manufacturer’s specifications.
   • Reconnect any utilities you disconnected.

Advanced RV Lifting Techniques and Considerations

Beyond simple corner lifting, other scenarios might require different approaches to RV lifting and chassis stabilization.

Using Onboard Leveling Systems

Many modern motorhomes come equipped with automatic leveling systems. These systems typically use hydraulic or electric jacks that extend from the chassis.

• Operation: These systems are usually operated by a control panel inside the motorhome. You select “auto-level” or manually extend individual jacks.
• Limitations: While convenient for motorhome leveling, these systems are often not designed for the extreme lifting required for tire changes or significant undercarriage work. Always check your manual to see if your onboard system is rated for lifting a wheel off the ground.
• Maintenance: Keep the hydraulic fluid topped up and check for leaks in the hoses and cylinders.

Heavy-Duty Lifting for Major Repairs

For major repairs that require lifting the entire front or rear of the motorhome, you’ll need much heavier-duty equipment.

• Industrial Hydraulic Jacks: Consider using 10-ton or even 20-ton bottle or floor jacks.
• Multiple Jack Points: You might need to use jacks at multiple points on the chassis simultaneously, coordinated by your helper.
• Heavy-Duty Jack Stands: Ensure your jack stands are rated for the load and positioned at sturdy frame members.
• Professional Assistance: For major chassis work or if you are unsure about the process, it’s often best to seek assistance from a qualified RV mechanic or a mobile service.

Chassis Stabilization Techniques

Proper chassis stabilization is key to preventing the motorhome from shifting during maintenance.

• Beyond Jacks: While jacks lift, stabilizing jacks (often called “landing gear” on some RVs) are designed to prevent rocking and swaying when the motorhome is parked. These are usually deployed after the motorhome is leveled.
• Load Distribution: Use wide, flat pads under all jack points (both lifting jacks and stabilizing jacks) to distribute weight and prevent sinking.
• Secure Environment: Ensure the area around the motorhome remains clear and secure while it is elevated.

Common Mistakes to Avoid When Jacking an RV

• Using the wrong jacking points: This is the most frequent and potentially damaging mistake.
• Using inadequate equipment: Jacks or jack stands that are not rated for the motorhome’s weight are dangerous.
• Working on uneven or soft ground: This increases the risk of the jack or supports sinking or tipping.
• Not using jack stands: Relying solely on a jack to support the vehicle while working underneath is extremely risky.
• Not chocking the wheels: This can lead to the motorhome rolling off the jack.
• Rushing the process: Take your time and work deliberately and carefully.
• Not checking the manual: Skipping the owner’s manual is a recipe for disaster.

Maintaining Your Jacking Equipment

Your jacks and jack stands are critical safety tools. Proper maintenance ensures they are reliable.

• Cleanliness: Keep your jacks clean and free of dirt and debris. Wipe them down after each use.
• Lubrication: Lightly lubricate moving parts according to the manufacturer’s instructions.
• Hydraulic Fluid: For hydraulic jacks, check the fluid level regularly and top up with the recommended type of hydraulic fluid if necessary. Inspect for leaks.
• Inspection: Before each use, inspect all jacks and jack stands for any signs of damage, wear, or bending. Do not use any equipment that appears compromised.

Frequently Asked Questions (FAQ)

Q1: Can I use car jacks to lift my motorhome?

A1: Generally, no. Car jacks are designed for much lighter loads and lack the height and stability needed for most motorhomes. Using them can be extremely dangerous and will likely damage both the jack and your motorhome.

Q2: How high do I need to lift my motorhome for a tire change?

A2: You only need to lift the motorhome enough to clear the flat tire. This means lifting it just high enough so the inflated tire can slide off the wheel studs. Measure the height of your flat tire and add a couple of inches for clearance.

Q3: What is the difference between stabilizing jacks and hydraulic jacks?

A3: Hydraulic jacks are designed to lift heavy loads, typically to change a tire or perform repairs. Stabilizing jacks (also known as leveling jacks) are usually found on the corners of motorhomes and are designed to take the weight off the suspension, prevent rocking, and help with motorhome leveling. They are not typically designed for lifting the entire vehicle.

Q4: Where are the best jacking points on a motorhome?

A4: The best jacking points are always specified in your motorhome’s owner’s manual. These are reinforced areas of the chassis or frame that are designed to safely bear the load. Common areas include reinforced sections of the frame near the axles. Never guess; always refer to your manual.

Q5: How do I ensure my motorhome is stable when lifted?

A5: Ensure you are on a level, firm surface. Use sturdy wood blocks or leveling blocks under your jack’s base. Crucially, always use properly rated jack stands and lower the vehicle onto them, taking the primary load off the jack. Gently push on the vehicle to confirm stability.

Q6: Can I use RV leveling blocks to lift my motorhome?

A6: RV leveling blocks are primarily used to achieve a level parking position when the motorhome is already resting on its tires or stabilizers. They are not typically strong enough to be used as the primary lifting mechanism for a whole motorhome or to support it while working underneath. You might use them to create a stable base for a jack, but not as the sole support.

By following these detailed steps and safety guidelines, you can confidently and safely jack up your motorhome for essential maintenance and repairs. Always remember that safety comes first, and when in doubt, consult a professional.
