Design and Build Quality
You’ll appreciate the straightforward, rugged design that prioritizes functionality. The steel construction with a rust-inhibitive coating gives the bin durability against road grime and moisture, while the geometry is optimized to fit common RV frame configurations without interfering with other undercarriage components.
Materials and corrosion resistance
The steel components are treated with a rust-inhibitive coating, which reduces the chance of corrosion in typical road environments. While the coating helps, you should still inspect and touch up any chips or scratches over time to maximize lifespan.
Structural integrity and load rating
Each bin is rated to hold up to 100 lbs, which is suitable for a variety of items like tools, hoses, leveling blocks, cleaning supplies, and small camping gear. The bolt-on mounting design ensures a secure attachment to your RV frame, so you won’t worry about a rattling or insecure bin when you’re driving.
Sizes and Fitment Options
You’ll need to pick the right size to match your RV layout and storage needs. Lippert offers multiple sizes to accommodate different frame geometries and cargo needs, including a spare tire carrier option.
Which size should you choose?
If you have plenty of under-chassis length and want maximum volume, the Large (96″ x 21″) model gives you long, continuous storage. If your frame has cross-members, tanks, or other obstructions, the Standard size may be a better fit. The Standard with Spare Tire Carrier keeps a spare tire handy without sacrificing too much storage capacity. Measure your frame clearance and obstacles before ordering to ensure compatibility.
How the spare tire carrier option works
The spare tire carrier is an integrated or optional mount that lets you store a spare tire in an accessible location. You’ll find this useful if your current spare is stored in an awkward location or inside your coach where it takes up valuable space. The carrier is designed for easy access so you can get to the spare quickly when needed.
Installation Process
You’ll want to know what to expect during installation so it’s not a surprise weekend project. The unit bolts to the frame and typically uses existing bolt patterns or supplied hardware, depending on your RV model.
Tools and time required
You’ll generally need basic hand tools: socket set, wrenches, drill (if holes are not predrilled), measuring tape, level, and a torque wrench. Installation time can vary depending on access and whether you need to drill new holes; plan for a few hours for one person and less if you have help.
Step-by-step overview
You’ll follow these broad steps when installing the unit:
- Measure and test-fit the bin along the frame to find the best location.
- Mark mounting points, ensuring you avoid wiring, plumbing, and structural obstructions.
- Drill mounting holes if necessary (use proper bit size for included bolts).
- Bolt the mounting brackets or bin to the frame, using washers and lock nuts as needed.
- Tighten bolts to a snug setting, then to manufacturer-recommended torque if provided.
- Test the slide mechanism and spring-loaded latch; make adjustments to alignment if needed.
Be sure to follow any Lippert-specific instructions included with the product. If you’re unsure about drilling or bolting into the frame, consult an RV shop or technician.
Access and Ease of Use
You’ll likely use the bin many times while traveling, so access and operation matter. The spring-loaded latch system makes sliding the compartment in and out smooth and convenient, and the bolt-on installation keeps the bin secure while allowing quick retrieval of stored items.
Spring-loaded latch benefits
The spring-loaded latch keeps the bin stable while driving but releases easily so you can slide the compartment out without wrestling with a stuck door or heavy latch. You’ll find the motion intuitive and user-friendly, especially if you store frequently used items.
How the sliding mechanism performs
The sliding mechanism is designed to minimize rattles and binding when aligned properly. Regular lubrication of the sliding components can keep motion smooth. If alignment is off or mounting hardware becomes loose over time, the slide may bind, so occasional checks are a good habit.
Security and Weather Resistance
You’ll want to protect your belongings from theft and elements. This unit offers secure mounting and a latching mechanism, but you should consider additional security measures for high-value items.
Theft deterrence
The bolt-on design provides a secure attachment to the frame, which is a deterrent compared to soft bags or unsecured crates. To further secure your items, you can add padlocks or other locking solutions to the latch area. For additional theft protection, consider alarm sensors or wheel locks for the RV itself.
Weather sealing and protection
The rust-inhibitive coating helps protect metal components from corrosion, and the box design keeps direct water and dirt out of the storage area. However, you should expect some moisture and dirt over time due to road spray. Use sealed containers, plastic bins, or weather-resistant bags inside the compartment for items that must stay dry.
Weight Capacity and Practical Use
You’ll need to plan storage around the 100-lb per bin capacity. That’s sufficient for many common items, but you’ll need to distribute weight wisely.
What you can realistically store
You can store leveling blocks, hoses, power cords, tools, folding chairs, and other camping gear comfortably. Heavier items like jacks, large spare tires, or fuel cans can approach the weight limit, so you should balance weight across multiple bins or re-evaluate placement for heavy gear.
Tips for weight distribution and safety
Keep heavy items close to the RV frame’s centerline and avoid creating an imbalanced load on one side. Secure items inside the bin to prevent shifting during travel. If you exceed the rating or have heavy specialized equipment, consult the RV manufacturer for appropriate mounting locations or professional reinforcement.
Maintenance and Care
A little maintenance will keep the unit functioning smoothly for years. You’ll want to inspect seals, hinges, and the latch periodically and perform basic cleaning.
Regular maintenance checklist
- Clean the exterior and interior with mild soap and water as needed.
- Inspect the rust-inhibitive coating for scratches; touch up with suitable paint or primer.
- Lubricate the sliding mechanism with a dry lubricant or silicone spray to avoid dirt buildup.
- Check bolts and fasteners for tightness and retighten as necessary.
- Verify the latch spring tension and function; replace worn parts if needed.
Seasonal care
Before winter storage or long off-season periods, remove any moisture-sensitive items and wipe down the interior. Consider spraying a protective coating on exposed metal if you camp in salty or highly corrosive environments.
Weather and Road Performance
You’ll encounter various road and weather conditions, and this unit is designed to withstand typical challenges. That said, some environmental factors require special care.
Handling road debris and spray
The enclosed design will protect items from large debris but not from fine dust or water spray entirely. You’ll still want to use internal containers for items sensitive to moisture or dirt. If you drive on rough gravel roads frequently, check mounts and fasteners more often.
Cold and hot climates
In cold temperatures, the latch and sliding mechanism might stiffen; lubrication helps. In hot climates, the bin can trap heat, which could affect certain items like electronics or aerosol cans—store such things in temperature-tolerant cases or inside the coach.

Comparison with Alternatives
You’ll want to compare this option against other storage strategies. Here’s how the Lippert unit stacks up versus common alternatives.
Built-in bay compartments vs. under-chassis bins
Built-in bay compartments often offer more protection from water and road spray, but they usually reduce interior space and may be more expensive to add. Under-chassis bins like the Lippert unit are less intrusive and often simpler to install.
Plastic tote systems vs. steel under-chassis bins
Plastic totes are inexpensive and waterproof but can slide around and may not be as secure or aerodynamic. Steel under-chassis units bolt securely to the frame and provide a permanent, streamlined solution.
Aftermarket boxed carriers vs. OEM solutions
OEM boxed carriers might be custom-fitted and designed specifically for your RV, which can minimize fit issues. Aftermarket solutions like the Lippert 175180 offer broader compatibility, cost savings, and multiple size options, but you’ll need to verify fitment carefully.
Real-World Use Cases
You’ll likely have a few specific storage needs; here are some practical ways people use under-chassis storage bins.
Camping and outdoor gear
Store chairs, grills, tarps, and tools that you only need at the campsite. Having these items under the chassis keeps the interior tidy and accessible when you arrive.
Tow vehicle offloading and travel convenience
If you tow a vehicle, freeing up onboard space by moving bulky gear under the chassis makes loading the tow vehicle easier and reduces clutter inside both vehicles.
Emergency and repair kits
Keep a toolbox, tire repair kit, or roadside supplies in the bin so they’re close to the road and easy to access without crawling into the coach.
Troubleshooting Common Issues
You’ll want to know what to look for if things don’t go as planned. Here are typical issues and how to address them.
Sliding mechanism binds or sticks
Check for misalignment and loose mounting bolts. Clean the slide rails and lubricate with a dry-film lubricant. If the slide is damaged, replace worn components.
Latch doesn’t hold securely
Inspect the spring and latch catch for wear or deformation. Ensure the mounting alignment is correct and that the latch engages cleanly. Replace any worn parts and consider a small lock or retainer for extra security.
Corrosion or paint chipping
Touch up any chips promptly with rust-inhibitive primer and paint. Clean and inspect the unit regularly, and apply additional protective coatings if you operate in salty environments.
Accessories and Upgrades
You’ll likely want to customize or enhance the unit based on your needs. Here are common upgrades and accessories to consider.
Internal organization options
Add bins, trays, or dividers to keep items neatly separated and prevent shifting during travel. Use sealed dry bags for clothing or electronics.
Security add-ons
Install a padlockable hasp on the latch or add cable locks to further deter theft. For high-value gear, store items inside locked cases within the bin.
Weatherproofing and insulation
Add rubber seals or gasket strips around edges to reduce dust and water ingress. For items sensitive to temperature swings, install insulated containers or thermal wraps inside the bin.
Who Should Buy This
You’ll find this product ideal if you meet one of several profiles:

- You need a bolt-on, durable storage solution that’s easy to access.
- You carry a fair amount of camping gear, tools, or maintenance supplies and want them stored securely under the coach.
- You prefer a permanent storage solution over loose totes or temporary carriers.
If you only camp occasionally with minimal gear, a smaller or simpler solution might be more cost-effective. But if you’re a frequent traveler or full-timer, the Lippert unit becomes a valuable convenience.
Price vs. Value
You’ll evaluate the cost by considering materials, features, and installation. When priced competitively, the Lippert unit offers a strong balance of durability and convenience for RV owners who need additional storage. Factor in installation if you plan to have a shop fit it for you.
Is it worth the investment?
If you frequently carry the types of gear that benefit from being stored outside the living area, this unit can save space and improve organization—often justifying the expense through added convenience and usability. For those who rarely need external storage, the investment may be less compelling.
