Why RV Bed Lift Struts Stop Working and What to Check Before Replacing Them

An RV bed that once lifted easily can slowly become harder to raise. At first, the change may be small. You may need to use both hands instead of one, or the platform may stop staying open while you reach for something underneath. Eventually, the bed can feel as if all of its weight has returned to your arms.

When that happens, many RV owners assume the gas struts have simply worn out and need to be replaced. Sometimes that is exactly the problem. But a bed lift system can also become difficult to use because of a heavier mattress, loose mounting hardware, poor alignment, or a change in the way the bed is being used.

Understanding the difference can save time and prevent you from replacing a part that was not actually the cause of the problem.

How RV Bed Lift Struts Work

An RV bed lift strut is designed to provide lifting assistance as the bed platform moves around its hinge. It does not carry the entire weight of the bed in the same way a support post would. Instead, the gas spring works with the hinge and mounting points to make the platform easier to raise and help keep it open.

That is why the position of the mounting points matters.

The same gas spring can behave differently when its mounting position changes. The angle, distance from the hinge, length of the spring, and force rating all affect how the bed moves.

A properly matched system should make the bed easier to lift without making it difficult to close. If the system suddenly behaves differently, it is worth looking at the complete setup rather than immediately ordering stronger springs.

The Bed No Longer Stays Open

One of the clearest signs of a problem is a bed platform that slowly comes back down after you lift it.

A gas spring can lose force over time. Gas springs contain pressurized gas, and their seals and internal components can wear with use. RV storage areas also experience changes in temperature, vibration, and humidity, which means the hardware operates in a demanding environment.

A weakening strut is not the only possible explanation, though.

Check whether the mattress and bedding are the same as when the system was installed. Adding a heavier mattress can change the balance of the entire platform. A replacement mattress may look almost identical to the original while weighing considerably more.

This is one reason replacement struts should not be selected simply because they have the same length as the old ones.

A New Mattress Can Change Everything

Changing the mattress is an easy detail to overlook.

Suppose the original RV mattress was relatively light and the lift system was matched to it. Later, the owner replaces it with a thicker memory foam or hybrid mattress. The bed still fits the same space, so everything appears unchanged.

But the lift system is now working against a different load.

Recent RV replacement questions show this problem in practice. Owners have reported that a previously adequate gas spring setup no longer holds the bed properly after installing a heavier mattress.

The same principle applies to bedding. If the bed normally stays made with blankets, pillows, or other items, those items become part of the real operating load.

The important question is not simply how much the mattress weighs. It is how much the complete platform weighs when you normally use it.

When the Struts Are Not the Real Problem

A bed can become difficult to lift even when the gas springs are still functioning.

Start by looking at the hinges and mounting points. Loose screws, worn attachment points, damaged wood, or movement around a bracket can change the geometry of the system.

If one side of the platform moves differently from the other, look for a structural or alignment problem before changing the struts.

The gas springs should also move naturally through their operating range. They should not be forced sideways because of an incorrectly positioned mounting point. Side loading can affect how a gas spring operates and may put unnecessary stress on the hardware.

The RVGEEs describe similar considerations when discussing bed lift installation, including the importance of mounting position and testing the system with the mattress in place.

Listen to How the Bed Moves

Your ears can sometimes tell you something your eyes cannot.

A new squeak does not automatically mean a gas spring has failed. The sound could come from a hinge, mounting point, frame connection, or another moving part.

Pay attention to whether the bed rises evenly.

If one side moves first and the other side follows, the platform may not be moving freely. If the bed feels smooth but simply has less lifting assistance, the springs become more likely to be the area that needs attention.

If the movement is jerky, investigate the hinges and mounting points as well as the gas springs.

The goal is to identify the change in behavior before replacing anything.

Inspect the Gas Springs

A visual inspection can reveal useful clues.

Look at the cylinder and piston rod. The rod should be free from obvious damage, heavy corrosion, or deep scratches. Check around the cylinder for signs of leakage and inspect the connection points at both ends.

Also examine the brackets.

A gas spring can remain physically intact while the mounting hardware around it becomes loose or damaged. If a bracket has started pulling away from the platform or frame, installing a stronger spring without repairing the mounting area can create another problem.

The mounting structure has to handle the forces created during normal operation.

For RV compartment doors, similar failures can occur when mounting hardware becomes loose or damaged. The same basic principle applies to lift systems used around an RV: the spring and the structure supporting it have to work together.

Do Not Automatically Install a Stronger Spring

When a bed becomes difficult to hold open, installing a stronger gas spring may seem like the obvious solution.

It is not always the correct one.

A spring that is too weak may fail to provide enough assistance. A spring that is too strong can make the platform difficult to close and can place additional force on the hinges and mounting points.

The correct force depends on the application and the way the spring is installed.

This is particularly important when replacing an original system. Match the replacement to the manufacturer's specifications and the actual bed configuration rather than choosing the strongest available option.

A gas spring is not better simply because it has a higher force rating.

What to Check Before Buying Replacement Struts

Before ordering replacements, compare the current setup with the conditions when the bed worked properly.

Think about what has changed.

Has the mattress been replaced? Has the platform been modified? Has additional weight been added? Have the hinges become loose? Has a bracket moved? Does the bed now open to a different position?

Then record the relevant measurements and specifications from the existing system.

Depending on the application, these can include the extended length, compressed length, force rating, end fittings, and mounting arrangement.

If the original manufacturer's information is available, use it. If there is any uncertainty about the correct replacement, it is better to confirm the specifications than to guess.

When Replacement Makes Sense

If the bed has become consistently heavier to lift, the struts no longer provide adequate assistance, and the mounting hardware and hinges are in good condition, replacement may be the appropriate next step.

Hatchlift, for example, provides different RV bed lift configurations based on the particular bed and mattress setup rather than treating every RV bed as identical. Its current product information also recommends testing the finished system with the mattress and bedding in place.

That approach is useful regardless of which manufacturer you choose. The replacement should match the application, not simply thAn RV bed that once lifted easily can slowly become harder to raise.

How RV Bed Lift Struts Work

An RV bed lift strut is designed to provide lifting assistance as the bed platform moves around its hinge. It does not carry the entire weight of the bed in the same way a support post would.

When a Gas Spring Is Probably Not the First Thing to Replace

If the bed is rubbing against the frame, one hinge is loose, a bracket is pulling away from its mounting surface, or the platform is twisting during movement, replacing the gas springs may not solve the problem.

Repair the underlying issue first.

A lift system depends on several parts working together. The springs provide assistance, but they do not correct a damaged platform or poorly aligned hinge.

This is especially important on older RVs where years of vibration and repeated opening can affect screws, brackets, wood, and other mounting surfaces.

A Simple Way to Think About the Problem

When an RV bed lift starts behaving differently, ask three questions.

First, has the load changed?

Second, has the hardware or mounting position changed?

Third, has the lifting assistance itself become weaker?

Those three questions cover many of the common reasons a previously reliable bed lift becomes difficult to operate.

If the load has increased, the system may no longer be correctly matched to the bed. If the hardware has moved or become damaged, the mounting arrangement needs attention. If everything else remains unchanged and the assistance has gradually decreased, the gas springs may simply be reaching the end of their useful service life.

Frequently Asked Questions

How do I know if my RV bed lift struts are bad?

A bed that gradually becomes harder to lift or no longer stays open can indicate weakened struts. However, check the mattress weight, hinges, mounting brackets, and alignment before replacing them.

Can a heavier mattress affect an RV bed lift?

Yes. A heavier mattress changes the load on the lifting system. A setup that worked with the original mattress may provide less assistance after a heavier replacement is installed.

Should I use stronger gas springs if my RV bed will not stay open?

Not automatically. The correct spring force depends on the complete bed configuration and mounting geometry. A stronger spring can create excessive force when closing and may place additional stress on the mounting structure.

How often should RV bed lift struts be replaced?

There is no single replacement interval that applies to every RV. Service life depends on the strut design, usage, environment, load, and installation. Performance changes and visible damage are more useful indicators than a fixed calendar period.

Can I replace RV bed lift struts myself?

Some RV owners with suitable mechanical skills and tools can replace lift struts themselves. The exact procedure depends on the system. The bed should be supported safely during the work, and the manufacturer's installation instructions should be followed.

Conclusion

An RV bed lift rarely changes from working perfectly to failing without giving some indication first. A bed that becomes heavier, drops unexpectedly, moves unevenly, or develops unusual noises is telling you that something has changed.

The useful first step is not always buying a replacement strut. Look at the mattress, platform, hinges, brackets, mounting points, and movement of the bed. Once those areas have been checked, you can make a more informed decision about whether the gas springs actually need replacing.

A lift system works best when the spring, bed platform, hinges, and mounting structure are treated as one system. Understanding that relationship can help RV owners troubleshoot problems more accurately and avoid unnecessary replacements.
