OUR WORST RV FEAR! WE HAD FRAME FLEX | Lippert Mobile Tech Tells ALL!

Posted on by Tom

Recreational Vehicles (RVs) provide a unique and adventurous way to travel and explore the great outdoors. However, like any complex machinery, RVs are not immune to issues, and one of the significant concerns that owners may encounter is frame flex. In this blog post, we will delve into the causes, impacts, and potential solutions related to RV frame flex.

We had RV frame flex on our Columbus RV (Forest River) several years ago. Check out our recent video on the experience. So happy that Lippert (LCI) showed up with a welding truck to get us fixed up and back on the road!

I. What is RV Frame Flex?

At its core, RV frame flex refers to the bending or twisting of the vehicle’s frame under various conditions. The frame is the structural backbone of an RV, supporting the entire structure and ensuring its stability during travel. When the frame experiences flex, it can lead to a range of problems that impact both the vehicle’s performance and the comfort of its occupants.

II. Causes of RV Frame Flex:

  1. Road Conditions: Uneven roads, potholes, and rough terrains can subject an RV to constant vibrations and shocks, leading to frame flex over time. Long hours on less-than-ideal road surfaces can gradually weaken the frame’s integrity.
  2. Overloading: Loading an RV beyond its weight capacity can exert excessive stress on the frame. This is a common issue as RV owners may unintentionally carry more gear and belongings than recommended, leading to increased strain on the frame.
  3. Design Flaws: Some RVs may be more susceptible to frame flex due to design flaws or inadequate engineering. This could involve using subpar materials, insufficient cross-bracing, or inadequate welding, all of which contribute to frame weaknesses.

III. Impacts of RV Frame Flex:

  1. Structural Damage: Continuous frame flex can lead to structural damage, compromising the overall integrity of the RV. This may result in alignment issues, making the RV unsafe to drive and potentially causing additional wear and tear on other components.
  2. Leaks and Seal Failures: Frame flex can also contribute to seal failures, allowing water to infiltrate the RV. Water damage is a serious concern, as it can lead to mold growth, rot, and degradation of interior materials.
  3. Reduced Comfort: Frame flex often translates to a less comfortable ride for occupants. Excessive movement can cause furniture and appliances to shift, leading to an uncomfortable and potentially unsafe living environment.

IV. Detecting Frame Flex:

  1. Visual Inspection: Regular visual inspections of the RV’s frame can reveal signs of flex, such as visible cracks, weld separations, or areas of metal fatigue. Paying attention to any abnormalities can help catch potential issues before they escalate.
  2. Handling Issues: If an RV experiences changes in handling, such as swaying or drifting, it may be indicative of frame flex. Any unusual vibrations or noises during travel should also be investigated promptly.

V. Solutions to Address RV Frame Flex:

  1. Proactive Maintenance: Regular maintenance, including inspecting the frame and addressing issues promptly, is crucial. This includes checking for loose bolts, ensuring proper alignment, and verifying that the RV is within its recommended weight limits.
  2. Upgrading Suspension Systems: Enhancing the RV’s suspension system can help mitigate the impact of road vibrations and shocks, reducing the strain on the frame. Upgrading to high-quality shock absorbers and adding additional support systems, like sway bars, can contribute to a more stable ride.

  3. Professional Repairs: If frame flex is identified, seeking professional repairs from qualified technicians is essential. Welding and reinforcing weak points in the frame can restore structural integrity and prevent further damage.
  4. Weight Management: Being mindful of the RV’s weight limits and avoiding overloading is crucial. Distributing weight evenly and using proper storage solutions can contribute to reducing stress on the frame.

Conclusion:

RV frame flex is a common concern that, if left unaddressed, can lead to serious consequences for both the vehicle and its occupants. Owners must stay vigilant, conduct regular inspections, and take proactive measures to prevent and mitigate frame flex issues. By understanding the causes, recognizing the impacts, and implementing appropriate solutions, RV enthusiasts can ensure a safer and more enjoyable travel experience in their home on wheels.

    1. HI, My name is jimmy and I have been following you and others on this frame flex issue. The proper term would be plastic yielding or fracture by the way. I am now retired from the structure steel industry after 50 years and am getting ready to purchase my first RV. Having seen many of these frame failures you have been rereferring to it didn’t take long to see what the problem was. It is simply the size of the hollow steel sections (HSS), the means and methods used to connect these components at the pin box and upper platform to the riser, and the axle connection assemblies, or lack thereof, at the lower frame. However, the fix after the manufacturing level is much more complicated and costly. This is why Lippert and Grand Design have been somewhat silent. Having listened to a certain You Tube channel and Lippert engineering comments on how foam filled sidewall are part of the structural steel support framing system, total BS, I thought I would get a little involved. I would welcome the opportunity to have a short conversation with to relate my structure knowledge on the subject. To write it all down would take some time.
