When temperatures drop and travel plans pause, proper winter storage protects your motorhome investment. For RVs equipped with LiquidSpring® Smart Suspension™, a few additional checks ensure your suspension system performs flawlessly when spring arrives.
In this guide:
- Essential pre-storage suspension inspection
- LiquidSpring-specific maintenance procedures
- Cold weather protection strategies
- Spring preparation checklist
Pre-Storage Suspension Checklist
Inspect System Components
Walk around your motorhome and visually inspect each LiquidSpring strut:
- Check for any fluid leaks around seals
- Look for physical damage to strut bodies
- Verify all mounting hardware remains tight
- Examine the five-link suspension components for wear
If you notice any issues, contact your LiquidSpring dealer before storage rather than waiting until spring.
Verify Fluid Levels
LiquidSpring systems include clear level indicators on the fluid reservoir. Before storing your RV:
- Park on level ground
- Check the fluid level indicator
- Top off if needed. Be sure to only use the compressible silicon fluid available from LiquidSpring.
- Note the level for comparison when you bring the RV out of storage
The compressible silicone fluid in your LiquidSpring system remains stable across temperature ranges, unlike air suspension systems that can lose pressure in cold weather. The silicone fluid expands and contracts with temperature. If the motorhome is stored in a cold environment, it may settle down onto the bump stops. This is normal. Once you start the coach, the system will automatically bring it back to its proper ride height.
Check the Desiccant Filter
The desiccant silica filter eliminates moisture from your suspension system. Before winter storage:
- Locate the filter housing on your power control module
- Check the indicator color (should be purple, not pink)
- Replace if the indicator shows pink (moisture saturation)
- Keep a spare filter on hand for spring inspection
In humid climates, filters may need replacement more frequently. Winter storage presents an ideal time for this simple maintenance task.
Torque Verification (Recently Installed Systems)
If your LiquidSpring system was installed within the past 1,000 miles, verify torque settings before long-term storage:
- All mounting bolts should be checked
- Refer to installation documentation for specifications
- Your dealer can perform this verification during pre-storage service
After the initial 1,000-mile check, LiquidSpring systems require only periodic inspections, making them ideal for seasonal RV use.
Cold Weather Protection Strategies
Ideal Storage Conditions
LiquidSpring suspension handles temperature extremes well, but indoor storage provides optimal protection:
- Climate-controlled storage: Ideal but not required
- Covered outdoor storage: Protects from ice and snow accumulation
- Uncovered storage: Acceptable with proper preparation
Unlike air suspension systems that can develop issues from temperature fluctuations, LiquidSpring’s liquid-based technology maintains consistent performance regardless of ambient temperature. The system may rise or settle depending on temperature, which is completely normal.
Battery Maintenance
Your LiquidSpring system’s onboard microprocessor requires minimal power, but battery maintenance remains important:
- Maintain battery charge to prevent system resets
- Use a battery maintainer if storing for extended periods
- Disconnect batteries if storing longer than 3 months
- The system will automatically recalibrate when power is restored
Standard RV Winterization
Beyond suspension care, complete these essential winterization tasks:
Plumbing System:
- Drain all water tanks and lines
- Add RV antifreeze to prevent freeze damage
- Bypass water heater before adding antifreeze
- Run antifreeze through all fixtures
Appliances:
- Clean and defrost refrigerator (leave doors open)
- Drain and clean black and gray tanks
- Disconnect propane and store tanks properly
- Clean and cover appliance vents
Exterior Protection:
- Wash and wax exterior surfaces
- Clean and condition roof seals
- Cover windows and vents
- Apply protectant to rubber seals and weatherstripping
Interior Preparation:
- Remove all perishable items
- Clean thoroughly to prevent mold and pests
- Open cabinets and drawers for air circulation
- Place moisture absorbers throughout
Spring Preparation Checklist
When you’re ready to hit the road again, perform these LiquidSpring checks:
Pre-Season Suspension Inspection
Visual Inspection:
- Check all struts for leaks or damage
- Verify mounting hardware remains secure
- Inspect five-link components for wear
- Look for any rodent damage to wiring
Fluid System Check:
- Verify fluid level matches pre-storage measurement
- Check desiccant filter color indicator
- Replace filter if pink (moisture saturated)
- Top off fluid if needed
System Test:
- Start the RV and let systems initialize
- Test Comfort, Normal, and Sport modes
- Verify Tru-Earth Leveling® functions properly
- Listen for any unusual sounds during operation
Test Drive Evaluation
Before your first major trip:
- Take a short test drive on varied road surfaces
- Note any changes in ride quality
- Test the suspension’s response to load changes
- Verify automatic load-leveling functions properly
If anything feels different from last season, contact your LiquidSpring dealer for evaluation. Most issues stem from simple adjustments rather than significant problems.
Common Winter Storage Questions
Q: Can I store my RV outside in freezing temperatures with LiquidSpring? Yes. Unlike air suspension systems that lose pressure in cold weather, LiquidSpring’s compressible silicone fluid remains stable across temperature extremes. The system handles cold weather storage without special procedures.
Q: How often should I check on my stored RV? Monthly inspections catch potential issues early. During each visit, walk around and visually inspect your LiquidSpring struts along with standard RV checks like tire pressure and exterior condition.
Q: Should I run my RV periodically during winter storage? If storing for extended periods (3+ months), starting your RV monthly maintains battery charge and keeps systems operational. Let the engine run for 20-30 minutes to circulate fluids and recharge batteries.
Q: What if I discover a leak during pre-storage inspection? Contact your LiquidSpring dealer immediately. Most leaks stem from simple seal issues that are easy to repair. Addressing them before storage prevents more significant problems come spring.
Q: Can I perform suspension maintenance myself? Basic checks like fluid level verification and desiccant filter replacement are straightforward DIY tasks. For anything beyond these simple procedures, contact your authorized LiquidSpring dealer.
Full-Time RVers: Special Considerations
If you live in your RV full-time, traditional winter storage doesn’t apply. However, cold-weather operation requires awareness:
Cold Climate Operation:
- LiquidSpring performs normally in all temperatures
- Systems automatically adjust for temperature variations
- No special procedures needed for cold-weather travel
- Regular maintenance schedule remains the same
Snowbird Travel:
- Inspect suspension before long migrations
- Verify fluid levels at seasonal destinations
- Check desiccant filter when crossing climate zones
- Keep dealer contact information for your winter location
Protecting Your Premium Investment
Your LiquidSpring suspension represents a significant upgrade to your motorhome—one that delivers measurable benefits in comfort, handling, and safety. Proper winter storage and maintenance protect this investment and ensure years of reliable performance.
The minimal maintenance requirements make LiquidSpring ideal for seasonal RV use. A few simple checks before storage and again in spring keep your suspension performing at its best. Compare this to air suspension systems that require regular pressure checks and often develop leaks during extended storage.
When you pull your motorhome out of storage next spring, your LiquidSpring system will respond exactly as it did last fall—automatically adjusting to road conditions and delivering the smooth, controlled ride you expect.
Need help with winter maintenance? Contact your authorized LiquidSpring dealer for professional service. Most dealers offer pre-storage inspections that verify your suspension system is ready for winter.
