Camco Hot Water Hybrid Heat Kit
The Camco Hybrid Heat Kit converts an existing LP gas water heater to 120V electricity on demand, allowing propane savings when electric power is available. It includes an on/off power switch with a mounting bracket, a fully adjustable thermostat, and all necessary power cords and color-coded wire assemblies. This setup is designed for RVs and trailers using 6-gallon heaters, enabling efficient heat delivery and flexibility during cold trips. Its electric-on-demand approach can help reduce propane use while maintaining warm water for showers and sinks in trailers.

The Briidea Hybrid Heat Kit expands RV heating options by combining LPG and electric heating for water tanks up to six gallons. It aims to provide safer and potentially lower-cost heating, especially when external electric power is available. The kit includes brass bushings for compatibility with most Atwood and Suburban tanks, color-coded cords for simple installation, and an independent switch with a mounting bracket. The adjustable thermostat helps maintain a steady water temperature, preventing freezing in frigid environments and supporting a smoother hot-water experience during travel.
FOGATTI RV Furnace 35,000 BTU
This complete RV furnace unit includes a motor, chamber, housing, and thermostat, delivering up to 35,000 BTU with adjustable power levels. The system provides rapid heating with up to 260 CFM airflow, designed for campers, motorhomes, and trailers. Its smart control features, including multiple modes and fault monitoring, supports reliable operation in winter conditions. Because it is a full furnace rather than a simple heater cartridge, this option is suitable for those seeking robust, centralized heating in enclosed trailers and RVs.
RV Holding Tank Heater Pad 12″x18″
The 12″ x 18″ RV water tank heater pad includes an automatic thermostat to activate around 45°F and shut off near 68°F, protecting holding tanks from freezing. It is designed for RV water tanks up to 50 gallons, covering fresh, grey, and black tanks. The pad’s compact design enables flexible placement in trailers and campers, offering a simple and energy-conscious way to maintain water availability in cold weather. Its integration with existing tanks makes it a practical option for winter RV travel and storage.
Boat Engine Compartment Heater 400W
Designed for marine and RV applications, this 400W heater uses a self-regulating PTC element to maintain stable temperatures in engine compartments and other enclosed spaces. It features a sealed electronics module and a waterproof fan for reliability in damp environments. The unit’s compact form and versatile mounting options enable use in under-vehicle areas, well houses, and other enclosed trailer compartments, helping prevent freezing of critical components during winter storage or travel.
60 Led Van Interior Light Kits
Though primarily a lighting kit, these 60-LED modules support interior visibility for cold-weather setups and maintenance tasks inside enclosed trailers and vans. Easy installation with strong double-sided tape, optional screws, and DIY-friendly wiring helps riders add bright, energy-efficient lighting to improve safety and comfort during winter trips when heating systems are in use or being serviced.
120 Led Van Interior Light Kits
This larger 120-LED interior lighting set provides focused illumination for large trailers and vans. High-brightness LEDs, durable housings, and easy plug-and-play installation offer a practical lighting upgrade to support winter maintenance, safe navigation, and comfort inside enclosed trailers and RVs. The modules are designed for flexible configurations, making it easier to create a warm, well-lit interior for colder months.
Buying Guide: Key Factors For Enclosed Trailer Heater Kits
- Power source compatibility: Determine whether you want propane/LPG, 12V DC or 120V AC electric heating, or a hybrid approach. Electric options require a reliable power supply; propane models need venting and fuel supply planning.
- Heat output and area: Match BTU ratings (or watts) to your trailer’s volume and insulation. For water tanks, ensure the kit accommodates your tank size and applies to fresh, grey, and black water as needed.
- Control and safety features: Look for thermostats, automatic cutoffs, fault monitoring, and temperature ranges that prevent freezing without overheating living space.
- Installation complexity: Some kits are modular and easier to retrofit; others require professional installation, especially for gas appliances or integrated furnace units.
- Tank protection: For all cold-weather setups, ensure tanks and pipes have frost protection and that wiring is rated for damp environments inside trailers.
- Durability and warranty: Choose rugged components with corrosion resistance and a reliable warranty, particularly for marine or all-weather use.
- Ventilation and safety clearances: Gas furnaces and LP conversions require proper venting, clearance from combustibles, and adherence to local codes.
When selecting a heater kit for enclosed trailers, consider how you use the trailer—season length, climate, and power access. Hybrid systems offer flexibility in areas with fluctuating power availability, while dedicated propane or electric solutions may provide simplicity and lower operating costs in specific scenarios. Always follow manufacturer installation instructions and local codes to ensure safe and effective operation in your environment.
