6 Best RV Storage Struts For Heavy Exterior Compartments
Upgrade your RV with our top 6 storage struts. We analyze durability and lift capacity to ensure your heavy exterior compartments stay open and secure.
Nothing ruins a campsite setup faster than a heavy storage bay door that refuses to stay open or slams shut the moment you reach for your gear. Upgrading your RV’s gas struts is one of the most high-impact, low-cost modifications you can make to improve your daily workflow on the road. Let’s dive into the best hardware to keep those heavy doors locked in the open position so you can focus on the trip, not the equipment.

Understanding RV Compartment Strut Dynamics
At their core, gas struts are pressurized cylinders that use nitrogen gas to provide a controlled lift and hold. In an RV, they function as a counterbalance, essentially neutralizing the weight of the door so it feels weightless when you lift it. If your struts are failing, you’re fighting gravity every time you grab a leveling block or a power cord.
The physics here is simple but unforgiving: if the force rating of the strut is too low, the door won’t stay up; if it’s too high, you’ll struggle to close it or risk bending the mounting brackets. You need to find the "Goldilocks" zone where the strut provides enough support to keep the door open in wind, but not so much that you’re wrestling with the hatch every time you close it.
Calculating Required Force for Heavy Doors
Before buying replacements, you need to calculate the weight of your door. A common mistake is simply buying the "strongest" strut available, which can actually cause structural damage to your fiberglass or aluminum compartment frame. You want to match the force (measured in pounds) to the weight of the door plus a small buffer for accessories like bike racks or mounted tools.
To get an accurate estimate, use a luggage scale to measure the force required to lift the door at the point where the strut will be mounted. If you can’t get a scale, a general rule of thumb is to measure the door length and weight, then consult the manufacturer’s load chart. Remember, the geometry of the mounting point matters just as much as the strut’s raw power.
Suspa C16-08054 Gas Springs for Utility Bays
Suspa is the gold standard for OEM replacements, and the C16-08054 is a workhorse that fits a massive range of RV utility bays. These struts are known for their consistent pressure curve, meaning they don’t lose their "oomph" after a few months of temperature fluctuations. If you want a "set it and forget it" solution that mirrors the quality of your original factory parts, this is the one.
They are particularly well-suited for heavy-duty exterior bays that house generators or heavy tools. Because they are designed for industrial-grade longevity, they handle the vibration of highway travel exceptionally well. If your goal is reliability over flashiness, buy these and you won’t have to think about them again for years.
Camco 42753 Heavy Duty Struts for Storage
Camco is a household name in the RV world for a reason: they design products specifically for the unique environment of mobile living. The 42753 struts are built with a focus on corrosion resistance, which is essential if you spend time in coastal areas or regions with high humidity. These struts feel robust, and the mounting hardware provided is generally a step above the generic alternatives.
These are the right choice if you are tired of your current struts rusting or losing pressure during the off-season. They offer a very predictable, smooth lift that prevents that jarring "snap" at the end of the opening stroke. If you’re looking for a reliable, widely available upgrade that fits most standard storage doors, Camco is a solid, safe bet.
Arana 20-Inch 100lb Force Gas Strut Set
Lift heavy lids (85-110 lbs) with these 20-inch gas struts, providing 100 lbs of force per strut. Adjustable L-brackets ensure easy installation for trap doors, hatches, and more.
If you have massive, heavy basement doors or a custom-built storage hatch, the Arana 100lb struts are likely what you need. These are high-force units designed to handle significant weight without buckling. Because they come in a set, you get perfectly matched tension, which is crucial for preventing the door from twisting or warping over time.
Be careful with these, however—100lbs of force is substantial. Only use these if your door is heavy enough to warrant that much lift; otherwise, you might find yourself needing to use both hands just to pull the door shut. If you have a heavy-duty compartment door that always feels like a burden, these are the heavy-lifters that will finally make it feel light.
Vepagoo 15-Inch 60lb Replacement Struts
Not every compartment door requires massive force; in fact, putting 100lb struts on a small, lightweight door is a recipe for broken hinges. The Vepagoo 15-inch struts are perfect for those mid-sized exterior compartments where you need a bit of help but don’t want to overdo it. They are compact, easy to install, and provide a very smooth, controlled motion.
These are ideal for the DIYer who is replacing struts on smaller side-bays or outdoor kitchen hatches. They offer a great balance of price and performance, making them an excellent choice for a fleet-wide replacement if your RV is starting to show its age. If you’re looking for a cost-effective way to refresh your RV’s utility, start here.
Maxpow 20-Inch 80lb Universal Lift Supports
Maxpow has carved out a niche by offering "universal" fitments that work across a wide variety of applications. The 20-inch, 80lb model is a versatile middle-ground for those who aren’t quite sure of their exact factory specs. They are beefy enough for most standard storage bays but not so aggressive that they become difficult to operate.
These are best for the RV owner who wants a balance between strength and accessibility. The build quality is surprisingly high for the price point, and they feature a solid seal that keeps the gas inside even after years of use. If you want a dependable, mid-range strut that will handle 90% of standard RV storage door scenarios, Maxpow is your go-to.
Stabilus Lift-O-Mat Struts for RV Hatches
Stabilus is a premium brand often found on high-end European motorhomes and luxury coaches. Their Lift-O-Mat line is engineering at its finest, featuring a proprietary sealing system that provides arguably the smoothest operation on the market. If you have a high-end rig and want to maintain that "luxury" feel every time you open a compartment, these are worth the extra investment.
These struts are perfect for someone who appreciates precision engineering and wants to avoid the "cheap" feel of generic hardware. They are incredibly durable and resistant to the extreme temperature swings of desert or mountain camping. If you’re willing to pay a premium for a product that feels like it belongs on a million-dollar coach, look no further.
Proper Installation and Mounting Techniques
Installing new struts is simple, but the orientation is critical. Always install the strut with the piston rod pointing downward whenever possible. This ensures that the internal oil seal stays lubricated, which significantly extends the life of the strut and prevents the "stuttering" motion often seen in improperly installed units.
Take the time to clean your mounting ball studs before snapping the new struts on. If the ball studs are worn or rusted, replace them at the same time—it costs almost nothing and prevents the new strut from popping off under load. Tighten your hardware securely, but don’t over-torque, as the fiberglass or plastic around the mount can easily crack.
Maintenance Tips for Long-Lasting Struts
Even the best struts will eventually lose pressure, but you can slow the process down. Periodically wipe the exposed metal rod with a clean, dry cloth to remove road grime and salt, which can score the seal and cause a leak. You can also apply a tiny amount of silicone lubricant to the rod to keep the seal supple.
Avoid leaving your compartments open during heavy wind storms, as the force of a gust can push a strut past its design limit and bend the rod. If you notice a door starting to "drift" downward, it’s usually time for a replacement before the door becomes a safety hazard. Treat your struts as wear items, and you’ll never have to worry about a door slamming on your head again.
Investing in quality gas struts is a small detail that fundamentally changes how you interact with your RV’s storage space. By matching the right force to your specific door weight and practicing proper installation, you’ll eliminate one of the most frustrating aspects of RV maintenance. Choose the hardware that fits your rig’s needs, and enjoy the peace of mind that comes with a perfectly balanced compartment door.
