peastorm Lockable Generator Box
Features include premium heavy-gauge steel construction with black powder coating for weather resistance, a lockable hasp for security (padlock not included), and a built-in ventilation system with a 12V cooling fan and exhaust vents. This box is best for RV owners who want a durable, theft-resistant enclosure that still maintains generator cooling. Best for: campers and RVs in areas where security and weather exposure matter. Caution: lock hardware is not included, so you’ll need a padlock to activate the anti-theft feature.
Stromberg Carlson Gen Secure II Generator Box
This aluminum generator box emphasizes enhanced security with an anti-theft design and is engineered for seamless installation on Stromberg Carlson trailer trays. It’s a durable, rust-resistant option suitable for RVs that travel with a trailer or need a secure transport enclosure. Best for: RV travelers who require reliable anti-theft protection and trailer compatibility. Limitation: designed primarily for specific trailer configurations, so verify fit with your trailer model before purchase.
Draviple Heavy Duty Generator Box
Designed to fit generators up to 30″ x 22″ x 24″, this soundproof enclosure features reinforced steel and advanced insulation to reduce noise. It uses a high-quality exhaust fan for improved ventilation and weather-resistant powder-coated steel for outdoor reliability. Best for: RVs and job sites where reducing noise is important without sacrificing airflow. Caution: ensure your generator’s outlet positioning aligns with the vent and exhaust layout to avoid restricted cable routing.
Fsehyue 24.4×15.7×19.7 Aluminium Toolbox
This fully sealed aluminum toolbox blocks rain and dust with rotatable ventilation holes that balance airflow. A gas-spring assisted lid (2 x 200N) makes access easy, and a locking knob supports theft deterrence. Best for: RVs or trucks needing a weatherproof, easy-access storage with controlled airflow. Limitation: the design emphasizes sealing, which may require periodic vent maintenance to keep airflow unobstructed over time.
Hudson SD Aluminum Generator Enclosure
Key strengths include efficient ventilation with louvered vents and an integrated high-speed cooling fan, combined with phenolic foam panels to reduce noise. The SD aluminum construction offers corrosion resistance and weather durability, supporting long outdoor use. Best for: RVs with longer operation times or higher heat generation. Caution: ensure your generator fits within the maximum internal dimensions and check clearance for venting paths.
Srehloe Aluminum Safety Generator Box
This box emphasizes adequate reserves with a 24″ x 16″ x 20″ footprint and a robust locking system for theft deterrence. It is adaptable for trailers, trucks, and RV bumpers, making it a flexible option for various external mounting scenarios. Best for: multi-scenario storage where a compact, lockable enclosure is needed. Caution: verify compatibility with your generator’s dimensions and the mounting space on your vehicle.
Buying Guide: Key Purchase Considerations
What size should you choose? Match the internal dimensions to your generator’s measurements plus clearance for airflow and cables. Consider whether you need a flush or raised mounting, and if your RV’s bumper, tongue, or trailer tray allows the box to sit safely and accessibly.
Which materials matter? Steel boxes are typically heavier but highly durable and weather-resistant; aluminum boxes resist corrosion and are lighter, which matters for frequent travel.
How important is ventilation? Look for boxes with exhaust vents, louvers, or fans to prevent overheating. Sealed designs help weatherproofing but ensure there is a controlled path for heat to escape.
What about security? Lockable enclosures deter theft. Check if padlocks are included or needed, and whether the enclosure uses reinforced hasps or anti-theft hardware.
Noise considerations: If quiet operation is a priority, seek boxes with sound-dampening panels or specialized foam linings near the exterior to minimize engine sound.
Weather readiness: For harsh climates, choose powder-coated or rust-resistant finishes and robust sealing against rain, snow, and humidity.
FAQ
- Will a generator box fit all RV generators? No single box fits every generator. Check internal dimensions and compare with your generator’s measurements plus needed clearance.
- Do these boxes require a separate padlock? In many cases, yes. Some models include lock provisions but padlocks are often not included.
- Is ventilation more important than weather sealing? Both are important. Adequate ventilation prevents overheating, while weather sealing protects against rain and dust. Balance both features when choosing.
- Can I mount these on trailers or bumpers? Several models are designed for trailer trays or external bumpers; verify compatibility with your trailer model before purchase.
- Do these boxes affect generator warranty? Box design should not void warranties if installed according to manufacturer guidelines, but check your specific warranty terms.
- Which material lasts longer outdoors? Aluminum generally resists corrosion better and is lighter, while steel offers robust durability with proper coating.
