6 RV Storage Bay Struts For Easier Access

We’ve all been there—trying to hold up a heavy basement compartment door with one shoulder while frantically digging for a shore power cord with the other. Properly functioning gas struts aren’t just a luxury; they are the difference between a seamless arrival at camp and a frustrating, door-slamming ordeal. Upgrading your storage bay supports is one of the most high-impact, low-effort modifications you can make to your rig.

Understanding RV Storage Bay Strut Mechanics

At their core, gas struts are pneumatic springs that use compressed nitrogen gas to provide a consistent lifting force. Unlike mechanical springs, they offer a dampened, controlled motion that prevents your compartment doors from slamming shut or flying open too aggressively.

Think of them as a counterbalance system that offsets the weight of the door. When you choose the right strut, the gas pressure does 90% of the work, allowing you to lift heavy exterior panels with a single finger. If your doors are sagging or won’t stay open, the internal seals have likely failed, causing the nitrogen to leak out over time.

Factors for Selecting the Correct Strut Force

Selecting the right "force" (measured in pounds or Newtons) is the most critical step in this process. If the strut is too weak, the door will drift down; if it’s too strong, you’ll find yourself wrestling to pull the door shut, which can eventually warp your hinges or compartment frames.

Always weigh your door before ordering replacements. A bathroom scale works perfectly for this: support the door at the handle end while the other end rests on the scale to get a rough estimate of the weight. You want the strut to be strong enough to hold the door open but not so powerful that it acts like a catapult.

Suspa C16-20358 Gas Springs for Heavy Doors

If you are running a Class A or a high-end fifth wheel with thick, insulated storage doors, the Suspa C16-20358 is the gold standard. These struts are built for durability and provide a consistent, firm lift that handles heavy exterior finish materials without hesitation.

I recommend these for anyone whose current doors feel like lead weights. They are reliable, widely available, and have a reputation for maintaining their pressure rating for years. If you have heavy-duty needs, skip the generic options and go straight for the Suspa; it’s the professional choice for a reason.

Camco 42721 Replacement Struts for Standard Bays

The Camco 42721 is the "everyman" of RV struts, designed to fit the vast majority of standard-sized storage bays found on travel trailers and smaller motorhomes. They are affordable, easy to find at any local RV supply shop, and get the job done without any unnecessary bells or whistles.

These are the perfect choice if you just need a functional, no-nonsense replacement for a door that’s starting to get tired. They aren’t intended for oversized, heavy custom doors, but for your standard pass-through storage, they are a solid, reliable investment.

Stabilus Lift-O-Mat Struts for Smooth Motion

Stabilus is the OEM supplier for many European vehicle manufacturers, and their Lift-O-Mat line is famous for its silky-smooth operation. If you hate the "jerky" feeling of cheap struts, these will be a revelation.

Their internal damping technology ensures the door opens in a fluid, controlled arc rather than snapping to the top of its travel. If you want your RV to feel like a premium piece of engineering every time you open a bay, spend the extra money on Stabilus. They are the definition of "buy once, cry once."

Industrial Gas Springs Inc. Custom Force Struts

Sometimes, your RV’s storage configuration is unique—perhaps you’ve added aftermarket shelving or heavy-duty locking mechanisms that changed the weight distribution of the door. In these cases, off-the-shelf struts might not cut it.

Industrial Gas Springs Inc. allows you to dial in specific force requirements that aren’t available in standard retail kits. If you’ve modified your rig and find that standard struts just don’t hold the weight, stop guessing and contact a custom manufacturer. It’s the only way to ensure your door stays exactly where you put it.

Ameritool Stainless Steel Struts for Coastal Use

If you spend your winters on the coast or travel through areas with high salt content in the air, standard steel struts will rust and seize within a few seasons. Ameritool’s stainless steel line is specifically designed to resist corrosion in harsh, humid environments.

These are an absolute must for full-timers who prioritize longevity over initial cost. You’ll pay a premium for the stainless construction, but you’ll avoid the headache of having to replace your struts every two years due to surface rust and seal failure.

Monroe Gas-Magnum Struts for Larger Compartments

Monroe is a household name in automotive suspension, and their Gas-Magnum line brings that same heavy-duty engineering to RV storage. These are robust, long-stroke struts designed for those massive, full-width compartment doors that span the entire width of a motorhome.

These struts are built for longevity and handle high-frequency use better than almost anything else on the market. If you are constantly in and out of your main basement storage, choose the Monroe; they are designed to take a beating and keep on lifting.

Measuring Your Current Strut Mounting Points

Before you click "buy," you must measure your "Extended Length" and "Compressed Length" accurately. Measure from the center of one mounting ball to the center of the other while the door is fully open for the extended length.

Don’t guess these numbers, as even a half-inch difference can prevent the door from closing properly or cause it to hit the frame. Always check your mounting brackets for wear while you’re at it; if the ball stud is worn down, even a new strut won’t provide a secure connection.

Installing Your New Storage Bay Gas Struts

Installation is generally a one-person job, but it’s much easier with a helper to hold the door in place. Use a flathead screwdriver to gently pry the retaining clip on the old strut end-fitting, then pop it off the ball stud.

When installing the new ones, ensure the cylinder (the thick part) is pointing upward. This keeps the internal oil seal lubricated, which is essential for the longevity of the strut. A quick wipe of the mounting ball with a clean cloth before snapping the new strut into place will ensure a smooth, quiet operation for years to come.

Replacing your gas struts is one of the most rewarding maintenance tasks you can tackle, instantly making your setup feel more polished and professional. By matching the right force and material to your specific storage needs, you eliminate one of the most common daily annoyances of RV life. Take the time to measure correctly, choose the right hardware for your environment, and enjoy the ease of a door that actually stays where you want it.
