1. Camco 40-Inch RV Bumper Storage Box: Best Overall
The Camco 40-Inch Bumper Box is a popular choice for good reason. In our research, it consistently earns high marks for its straightforward installation and solid aluminum build. The four locking latches distribute stress evenly, reducing the chance of lid warping. Owner feedback highlights that it fits most standard bumpers without modification, and the 40-inch length accommodates long items like sewer hoses and folding chairs.
However, we found a notable weakness: the box is not fully weather-sealed. Many owners report water and dust entering through the lid seam, especially in heavy rain. If you store sensitive items, you will need to add your own gasket or sealant. Also, the aluminum is relatively thin, so it can dent if overloaded. We recommend this for campers who need a lightweight, easy-to-install box for non-critical gear and are willing to add weatherstripping.
- Fits standard 4-inch square bumpers with included hardware
- Aluminum body resists rust and is lighter than steel
- Four locking latches provide even pressure and security
Pros: Easy to install with pre-drilled holes; Large capacity for hoses and leveling blocks
Cons: Not weatherproof; some owners report water intrusion
2. Barker Manufacturing 36-Inch Bumper Storage Box: Best Heavy-Duty
If durability is your top priority, the Barker Manufacturing 36-Inch box stands out. Our evaluation of owner feedback and spec sheets shows that its heavy-gauge steel and powder coating resist dents and rust far better than aluminum competitors. The included rubber gasket does a decent job keeping out moisture, though some owners still add extra sealant. The 9×9 profile is generous, fitting larger items like a small propane tank or extra tools.
The main drawback is weight. At nearly 30 pounds empty, it can stress a bumper that is not reinforced. We also heard complaints about the two latches being less secure than four-latch designs; some owners added a padlock hasp. This box is best for RVers who prioritize ruggedness and have a sturdy bumper. Skip it if you need lightweight installation or plan to mount on a light-duty rear bumper.
- Heavy-gauge steel with powder-coat finish for corrosion resistance
- Deep 9×9 profile fits larger items like propane tanks
- Includes rubber gasket for improved weather sealing
Pros: Exceptionally durable; can support heavy loads; Better weather resistance than most aluminum boxes
Cons: Heavy; adds significant weight to bumper
3. RecPro RV Bumper Storage Box 60-Inch: Best Extra-Long
The RecPro 60-Inch box is a niche pick for RVers who need to store extra-long items, such as fishing rods, awning poles, or telescoping ladders. In our research, owners appreciated the built-in handle, which makes it easier to detach and carry the box to a campsite. The aluminum construction keeps weight manageable, and the four latches close securely with a foam gasket that helps keep out dust.
However, the extended length introduces a problem: without a center support bracket, the box can sag over time, especially when loaded. Some owners fabricated additional brackets to prevent drooping. Also, the aluminum is only moderately thick, so heavy loads can cause denting. We recommend this box only if you have a reinforced bumper and need the extra length. Skip it if your bumper is standard or if you store heavy items; a shorter, steel box will hold up better.
- Extra-long 60-inch length for long items like fishing rods
- Aluminum construction with a built-in carry handle
- Four latches and a foam gasket for weather resistance
Pros: Excellent capacity for long gear; Handle makes it easier to remove and carry
Cons: Long length can sag if bumper support is weak
4. Stromberg Carlson Bumper Box 24-Inch: Best Compact
The Stromberg Carlson 24-Inch Bumper Box is designed for RVers with limited bumper space, such as those with a spare tire mount or a short rear overhang. In our evaluation, it is a solid choice for storing small essentials like chocks, a water hose, or electrical adapters. The aluminum body is lightweight and the powder coat resists chipping. Installation is simple with the included hardware.
That said, the compact size is its main limitation. You cannot fit long items or multiple bulky accessories. The two-latch design also means the lid can warp if overstuffed, and the key locks are basic; some owners reported keys breaking. This box is best for minimalists or those with very limited bumper space. Skip it if you need to carry a full sewer hose kit or larger gear.
- Compact size fits tight bumpers and spare tire mounts
- Lightweight aluminum with powder coat finish
- Two latches with key locks for basic security
Pros: Small footprint fits where larger boxes won't; Good value for occasional use
Cons: Limited capacity; only suitable for small items
5. Lippert Components Bumper Storage Box 48-Inch: Best Value
The Lippert 48-Inch box is the most budget-friendly option we researched. It offers a generous 48-inch length at a price that appeals to cost-conscious RVers. Owner feedback indicates it works well for storing light items like a fresh water hose and extension cords. The padlock tabs allow you to add your own lock for better security than the basic latches provide.
However, the thin aluminum construction is a real weakness. Many owners reported the box denting easily when loaded with heavy items or during travel. The two latches can also cause the lid to bow, allowing water to enter. We recommend this box only for light-duty use and if you are on a tight budget. Skip it if you need a box that can handle rough roads or heavy gear; invest in a steel or thicker aluminum model instead.
- Affordable price point for a 48-inch box
- Lightweight aluminum construction
- Two latches with padlock tabs for extra security
Pros: Very budget-friendly; Long enough for most hoses and leveling blocks
Cons: Thin aluminum; prone to denting and flexing
6. TorkLift Bumper Box 30-Inch Steel: Most Secure
The TorkLift 30-Inch Steel Box is built for security. In our research, it stands out for its welded steel construction and keyed latches that deter theft. The rubber seal around the lid is more effective than many competitors, though not completely waterproof. Owner reviews praise its ruggedness, with many noting it has held up for years without rust or damage.
The downsides are weight and size. At over 25 pounds, it can be a burden on a standard bumper. The 30-inch length is shorter than many options, limiting what you can store. Also, the keyed latches are convenient but some owners reported the keys breaking. This box is ideal for RVers who prioritize security and have a sturdy bumper. Skip it if you need a lightweight box or more storage length.
- Heavy-duty steel construction with welded seams
- Rubber seal helps keep out moisture and dust
- Keyed latches provide better security than standard latches
Pros: Very secure; latches lock with included keys; Sturdy build resists tampering
Cons: Heavy; adds noticeable weight to bumper
7. Vroom RV Bumper Storage Box 36-Inch Aluminum: Best Lightweight
The Vroom 36-Inch Aluminum Box is the lightest option we evaluated, making it a good choice for RVers with weak bumpers or those who frequently remove the box. Owner feedback indicates it is easy to install and the silver finish blends well with most RVs. It is adequate for storing light items like a water hose or small tools.
However, the thin aluminum construction is a significant drawback. Many owners reported that the box dents easily if anything heavy is placed inside, and the lid can warp after a few trips, compromising the seal. The two latches are not very secure, and the key locks feel flimsy. We recommend this box only for very light duty and short trips. Skip it if you plan to carry any weight or travel on rough roads; a sturdier box will last longer.
- Very lightweight; easy to install and remove
- Smooth silver finish matches many RVs
- Two latches with key locks
Pros: Extremely light; does not strain bumper; Easy to handle and mount solo
Cons: Thin aluminum; prone to denting and flexing
Frequently Asked Questions
Will a bumper storage box fit my RV bumper?
Most bumper boxes are designed for standard 4-inch square bumpers. Measure your bumper’s width and height before purchasing. Some boxes include adjustable brackets for non-standard sizes, but you may need additional hardware. Check the manufacturer’s specifications for bumper size compatibility.
How do I install a bumper storage box?
Installation typically involves sliding the box onto the bumper and securing it with bolts or set screws. Most boxes come with pre-drilled holes and hardware. You may need to drill pilot holes into the bumper. Always use a level to ensure the box is straight, and tighten bolts evenly to avoid warping the box.
Are bumper storage boxes waterproof?
Most are weather-resistant but not fully waterproof. They often include a foam gasket or rubber seal, but water can still enter through seams or around latches. For sensitive items, consider adding an aftermarket gasket or storing items in dry bags inside the box. Regular maintenance of seals helps reduce moisture intrusion.
Can I mount a storage box on a spare tire carrier?
Yes, some compact boxes are designed to mount on spare tire carriers or other locations. Look for boxes with adjustable mounting brackets or those specifically advertised for spare tire mounts. Ensure the carrier can support the weight of the box and its contents.
How much weight can a bumper storage box hold?
Weight capacity varies by model and bumper strength. Aluminum boxes typically hold 50-75 pounds, while steel boxes can hold 100 pounds or more. However, the bumper itself may have a lower weight limit. Check your RV owner’s manual for bumper capacity and do not exceed the combined weight of the box and contents.
Our Verdict
After researching and comparing the top options, the Camco 40-Inch Bumper Storage Box earns our top pick for its balance of ease of installation, capacity, and value. For those needing maximum durability, the Barker Manufacturing 36-Inch Steel Box is the runner-up, though it is heavier and requires a sturdy bumper. Choose based on your storage needs and bumper strength.
