Lippert Underchassis Unit: Best Heavy-Duty Bin

When it comes to pure structural integrity, the Lippert Underchassis storage unit stands alone. This is not a mere bracket; it is a full-fledged, weather-resistant storage bin that bolts directly to the chassis frame. It provides a secure, enclosed space that keeps jack pads, blocks, and leveling tools protected from the elements and road debris.

This solution is perfect for the full-time traveler or the boondocker who carries a heavy kit and refuses to sacrifice interior space. Because it is a rigid, enclosed box, it eliminates the risk of gear vibrating loose while driving down washboard roads. It represents a significant investment, but the durability justifies the cost for those who prioritize long-term equipment protection.

If you have a high-clearance rig and need a robust, lockable home for heavy leveling gear, this is the premier choice. Avoid this option only if your rig sits exceptionally low to the ground or if the mounting points are obstructed by critical plumbing or wiring runs.

MORryde Sliding Tray: Best for Easy Access

The MORryde sliding tray is the gold standard for those who dislike crawling into the dirt to retrieve equipment. By mounting a heavy-duty slide underneath the frame, you bring your gear to you. It transforms the awkward process of reaching under a low-profile vehicle into a smooth, ergonomic operation.

This system is ideal for users with mobility concerns or those tired of the “dig and drag” method of retrieving pads. The smooth ball-bearing slides ensure that even when the tray is loaded to its weight capacity, it deploys with minimal effort. It is a highly engineered solution that feels professional and eliminates the strain of standard undercarriage storage.

Select this if you prioritize convenience and have a chassis layout that allows for a horizontal slide path. Be aware that the hardware adds weight to the frame, so verify the weight limits of the mounting location before proceeding.

BAL Hide-A-Spare: The Most Versatile Bracket

The BAL Hide-A-Spare is a brilliant example of functional repurposing. Originally designed to store a spare tire beneath the frame, its adjustable arm configuration makes it an excellent candidate for holding custom platforms or heavy-duty containers filled with jack pads. Its strength lies in its versatility and adjustable width, which allows it to fit a wide range of frame sizes.

This bracket system is the best choice for the DIY-minded owner who wants a modular foundation. You can easily bolt a plywood platform or a heavy-duty plastic crate to the adjustable arms to create a custom cradle for your specific pad dimensions. It is rugged, reliable, and keeps your gear tucked safely behind the main frame rails.

If you want a tried-and-true mechanical system that offers flexibility for future changes, look no further. It requires a bit of manual setup, but it is an unbeatable platform for those who want a custom fit without fabricating a bracket from scratch.

Stromberg Carlson Carrier: Best Budget Pick

The Stromberg Carlson carrier is the quintessential utilitarian choice for those who want simplicity above all else. This bracket is designed for straightforward mounting, acting as a cradle that secures items tightly against the underside of the floor or chassis. It avoids the complexity of slides and bins, focusing instead on pure, reliable containment.

This is the right choice for the budget-conscious owner who wants to clear out the pass-through storage area without breaking the bank. It is exceptionally lightweight and provides a no-nonsense solution that is easy to install and maintain. It does not offer the “wow” factor of a sliding tray, but it gets the job done consistently.

If your requirements are minimal and you just need a sturdy place to strap or secure a stack of pads, this is the ideal bracket. It serves as a solid foundation for simple, effective storage that remains out of sight until needed.

E-Z Block Rack: Best for Leveling Blocks

The E-Z Block Rack takes a specific approach to a common problem: stacking interlocking leveling blocks. Instead of a generic bin, these brackets are shaped to accommodate the precise geometry of standard leveling pyramids. They are designed to keep the stack tight and prevent them from shifting during transit.

This rack is perfect for travelers who rely heavily on plastic leveling blocks rather than heavy wooden or rubber pads. Because the design allows for airflow, these racks help keep the blocks clean and ensure that mud and moisture can drain away easily after use. It is a specialized tool that performs its one function with high efficiency.

If you use stackable leveling squares exclusively, this system is superior to a generic storage box. It maximizes the use of space while ensuring your blocks are ready to deploy the moment you pull into a site.

DIY Bracket Solution: Best for a Custom Fit

Sometimes, the best solution is the one built specifically for the unique geometry of a particular chassis. A custom bracket made from angle iron or sturdy aluminum channel allows you to optimize every inch of undercarriage space. This is the path for those whose frame configuration prevents the use of standard off-the-shelf products.

A DIY approach is the best way to ensure the perfect fit for odd-sized jack pads or specific, heavy-duty rubber mats. By using high-grade stainless steel hardware and protective coatings, you can build a mount that is just as strong as, or stronger than, retail versions. It requires careful planning regarding ground clearance and weight distribution, but the result is entirely tailored to your needs.

Choose this only if you possess the necessary metalworking skills or have access to someone who does. When executed with high-quality materials, it provides a custom-fit solution that standard products simply cannot match.

Choosing a Bracket: Size Weight & Access

Before purchasing any bracket, measure the total height of your stack of pads when stored. It is a common mistake to ignore how the thickness of the bracket hardware reduces your available ground clearance. Always check the lowest point of your rig to ensure your storage solution does not become a hazard when transitioning over speed bumps or uneven terrain.

Weight distribution is another critical factor often overlooked by newcomers. Mounting heavy pads behind the rear axle can impact your rig’s tongue weight, while mounting them too far forward can affect overall handling. Aim for a balanced distribution that keeps the center of gravity stable without obstructing mechanical components.

• Weight Capacity: Ensure the bracket is rated for the total weight of the pads plus the weight of the mounting hardware itself.
• Access Path: Consider whether you can reach the release mechanism comfortably while the vehicle is parked on a slight incline or gravel.
• Clearance: Maintain at least 6-8 inches of ground clearance whenever possible to prevent impacts from road debris.

Installation: Mounting Securely & Safely

Securing a heavy bracket to a chassis requires more than simple self-tapping screws. The vibration of a moving vehicle will work these loose over time, potentially leading to the loss of gear or damage to the rig’s underside. Always use grade-5 or grade-8 bolts with locking nuts, or utilize self-drilling fasteners meant for structural frame work.

Be extremely cautious when drilling into any frame member. Never compromise the structural integrity of the main steel beams; instead, look for existing holes or use heavy-duty frame clamps that do not require drilling. If you are unsure about the safety of a mounting point, consult the manufacturer’s specifications for the vehicle frame.

Finally, use vibration-dampening washers or rubber spacers between the bracket and the frame. This prevents metal-on-metal wear and significantly reduces noise levels while driving. A secure mount is one that remains completely motionless even on the roughest roads.

Beyond Jack Pads: Other Undercarriage Uses

The brackets designed for jack pads are often perfectly suited for other essential but bulky items. Consider using these mounting points for leveling wheel chocks, spare water hoses, or even thin, long items like folding shovel handles or stabilizers. The key is to keep the weight balanced and ensure that everything is tightly strapped or enclosed.

Maintenance items are another common candidate for undercarriage storage. A spare length of sewer hose or a bag of leveling spacers can be stored in the same vicinity, provided the bracket system is secure. However, never store flammable materials or liquids beneath the chassis, as the proximity to heat sources and the risk of road debris impact pose a significant safety threat.

Always prioritize items that are water-resistant and durable. The undercarriage is a harsh environment, and anything stored there should be capable of withstanding moisture, salt, and rocks.

Road Salt Grime & Maintenance Concerns

The undercarriage is arguably the most neglected part of any vehicle, and mounting storage here increases your maintenance responsibility. Road salt is particularly aggressive; it will accelerate corrosion on both the bracket and the frame where the mount is attached. Regularly inspect the hardware for signs of rust and ensure that the connections remain tight every few thousand miles.

Grime buildup is inevitable, so choose brackets that are easy to hose off during your regular cleaning routine. If you live or travel in snowy climates where roads are salted, consider applying a frame-safe rust inhibitor to the mounting hardware annually. A little bit of proactive maintenance ensures that these brackets remain functional for the life of the rig.

If you find that a specific bracket is difficult to clean or shows signs of rapid oxidation, do not hesitate to replace it before it damages the chassis. The long-term protection of your frame is always more important than the convenience of a specific piece of storage equipment.

Effective undercarriage storage is about balancing accessibility with structural safety. By choosing the right bracket for your specific rig and maintaining it with an eye toward the harsh road environment, you can reclaim your interior storage space and simplify your setup routine. Invest in quality hardware, install it with precision, and enjoy the added efficiency on your next trip.
