6 Best Generator Mounting Brackets For Secure Travel

Hauling a heavy generator on the back of an RV is a classic balancing act between freedom and physics. If you don’t secure that weight properly, you aren’t just risking your equipment; you’re compromising the handling of your entire rig. Choosing the right mounting bracket is the difference between a smooth journey and a roadside disaster.

Generator Mounting: Safety and Weight Balance

When you mount a generator, you are adding significant dead weight to the rear of your vehicle, which acts like a lever on your chassis. This extra weight can lighten your steering axle, leading to dangerous sway or "porpoising" on the highway. Always check your RV’s tongue weight and rear axle capacity before bolting on a heavy tray.

Beyond the numbers, consider the center of gravity. A generator mounted too high or too far back exacerbates the pendulum effect during turns. Keep your load as low as possible and centered to maintain the stability your suspension was designed to handle.

Stromberg Carlson RV Generator Cargo Tray

The Stromberg Carlson tray is a workhorse for those who prioritize simplicity and raw strength. It mounts directly to your bumper, providing a solid steel platform that feels practically indestructible. It is the perfect choice for the RVer who wants a "set it and forget it" solution without needing a complex engineering degree to install.

However, you must ensure your RV bumper is rated to handle the weight, as many factory-installed bumpers are flimsy and prone to "bumper roll." If your bumper is sturdy, this tray is an excellent value. If your bumper is thin, skip this product unless you plan to add professional bracing.

GennyGo RV Bumper Generator Carrier Mount

The GennyGo system is designed specifically for those who struggle with the limitations of standard 4-inch square RV bumpers. It features a clever clamping mechanism that distributes weight more evenly, reducing the stress that typically causes bumper fatigue. It’s a smart, targeted solution for those who want to avoid welding or permanent modifications.

This carrier is ideal for the weekend warrior who needs a reliable mount that doesn’t require a complete overhaul of their rear storage area. It offers a great balance of ease-of-use and structural integrity. If you want a secure mount that respects the constraints of a stock RV bumper, this is your best bet.

Rack’em Manufacturing Generator Rack System

Rack’em takes a more modular approach, offering a system that feels like it was built for professional hauling. The design focuses on rigidity, minimizing the vibration that can shake a generator’s internal components to pieces over thousands of miles. It is built for those who travel primarily on rougher, secondary roads where vibration is a constant enemy.

The trade-off here is the weight of the rack itself; it’s heavy-duty steel, which adds to your total cargo load. If you have a high-end inverter generator that you want to protect from road shock, the investment in this heavy-duty system is justified. It is not for the weight-conscious traveler, but it is perfect for the serious off-grid enthusiast.

Stromberg Carlson CC-255 Aluminum Tray

If you are constantly battling your rig’s Gross Vehicle Weight Rating (GVWR), the CC-255 is a breath of fresh air. Being made of aluminum, it shaves off significant weight compared to steel alternatives while still offering ample space for most portable generators. It is rust-resistant, which makes it a standout choice for those traveling in coastal or humid environments.

The only downside is that aluminum can be more prone to fatigue cracking than steel if it’s overloaded or subjected to constant, extreme vibration. It is a fantastic choice for lighter, modern inverter generators. If you are hauling a massive, heavy-duty construction generator, look elsewhere; but for the average camper, this is a premium, weight-saving upgrade.

Hitch-Mounted Cargo Carrier for Generators

Hitch-mounted carriers are the most versatile option because they utilize the heavy-duty receiver hitch rather than the bumper. This allows for higher weight capacities and a more stable connection to the frame of the RV. It is the gold standard for anyone concerned about the structural integrity of their rear bumper.

The downside is that it extends your total vehicle length, which can make maneuvering in tight gas stations or parking spots a bit more stressful. If you have a spare hitch receiver or aren’t towing a secondary vehicle, this is objectively the safest way to carry a heavy load. It’s the most robust option for long-term travelers who prioritize safety above all else.

Camco Olympian RV Generator Mounting Base

Camco’s mounting base is less of a "rack" and more of a specialized platform designed to keep your generator stable on uneven ground or a tray. It’s a great auxiliary tool if you already have a cargo rack but need a way to bolt the generator down securely. It is simple, affordable, and gets the job done without unnecessary frills.

This isn’t a standalone mounting solution for the back of your RV, but rather a final layer of security for your setup. If you want a dedicated footprint that keeps your generator from sliding during transit, this base is a practical, low-cost addition. It’s a "must-have" for anyone who values vibration dampening and secure anchoring.

Custom Steel Fabricated Generator Brackets

Sometimes, the best solution is the one you build to fit your specific rig’s geometry. Custom steel brackets allow you to tie the mount directly into the RV’s frame rails, bypassing the bumper entirely. This is the only way to guarantee a "zero-flex" mount that can handle heavy loads over thousands of miles of washboard roads.

This path requires a welder and a good understanding of steel gauge and load distribution. It is not for everyone, but for the full-timer living off-grid, it is the ultimate upgrade. If you have the resources, a custom-fabricated mount provides a level of peace of mind that no off-the-shelf product can match.

Securing Your Generator for Rough Roads

Even the best bracket won’t save your generator if you don’t use high-quality tie-downs. Avoid cheap bungee cords at all costs; they will fail, and your generator will become a road hazard. Use heavy-duty, ratchet-style straps that are rated for at least twice the weight of your generator to account for the G-force of bumps.

Consider adding a secondary safety chain that attaches the generator frame to the RV chassis. If your primary straps loosen or fail, the chain acts as a final fail-safe. It’s a simple, low-cost habit that prevents catastrophic loss on the highway.

Maintenance Tips for Exterior Generator Mounts

Exterior mounts are exposed to road salt, rain, and constant vibration, all of which are enemies of metal. Every time you stop for gas, give your mount a quick visual inspection for stress cracks, especially near the weld points. Tighten all bolts every 500 miles, as vibration will inevitably cause them to loosen over time.

If you see rust appearing on your steel brackets, sand it down and touch it up with rust-inhibiting paint immediately. A little bit of preventative care ensures that your mount lasts as long as your rig. Treat your mounting system with the same respect you give your tires, and it will keep your gear safe for years to come.

Investing in a high-quality mounting system is about more than just convenience; it’s about protecting your power source and your vehicle’s integrity. Assess your rig’s specific weight capacities and your travel style before making a final decision. With the right bracket and proper maintenance, you can hit the road with the confidence that your power supply is secured for the long haul.
