FOGATTI 35,000 BTU Quiet RV Furnace
Type: Built-in gas furnace designed for campers, motorhomes, and travel trailers.
This unit provides a maximum 35,000 BTU output selectable across four power levels down to 17,000 BTU. It delivers 260 CFM airflow for fast cabin warm-up and includes a thermostat interface for regulated comfort. The product highlights a high-efficiency heat exchanger to maximize gas usage and extend travel range.
Additional features include three operating modes (quick heat/standard/sleep) and a fault monitor for diagnostics. The furnace is rated to output air up to 176°F to maintain performance in sub-zero conditions. Installation typically requires integration with existing ducting and propane/gas supply, so verify compatibility with your camper’s layout and fuel system.
VEVOR 8KW Diesel Heater

Type: Diesel air parking heater for standalone heating of cabins and vans.
This 8 kW diesel heater is designed for spaces roughly 215–269 ft² and uses a sandblasted aluminum heat exchanger for rapid heat production. It supports Bluetooth app control, an LCD panel, and a long-range remote for preheating convenience.
A notable capability is automatic altitude compensation up to 18,045 ft, which adjusts combustion parameters to maintain reliable operation at elevation. The unit provides fast warm-up within minutes and offers precise temperature control between roughly 46°F–96.8°F. Installation requires fuel line routing, exhaust, and proper mounting; professional installation is often recommended for safety and compliance.
Mr. Heater MH9BXRV Buddy Radiant Heater
Type: Portable propane radiant heater rated for indoor-safe use in RVs.
This compact heater ranges from 4,000 to 9,000 BTU and is suitable for spaces up to about 225 sq ft. It’s advertised as nearly 100% efficient for radiant heating and includes multiple safety shutdowns: tip-over, pilot outage, and low oxygen sensors.

Its portability makes it a convenient supplemental heater for short-term trips, quick warm-ups, or use in uninsulated portions of the camper. Note manufacturer guidance about high-altitude operation—units may shut off above certain elevations—and ensure ventilation and CO/CO2 monitoring when using portable fuel-burning heaters indoors.
Udekoo 12V RV Air Conditioner With Heat Pump
Type: Rooftop non-ducted air conditioner with integrated heat pump running on 12V DC.
This rooftop unit uses a 12V DC scroll compressor to provide both cooling and heating without idling the engine. It emphasizes energy efficiency by operating from the vehicle battery and claims high weather protection with an IPX6K rating and durable ABS housing resistant to UV and deformation.
The heat pump function supports cold-weather warmth when shore power or generator use is limited. Because it runs on 12V, this system is targeted toward boondockers and solar-equipped rigs, though it’s not recommended for use with starter batteries. Roof mounting considerations include available opening size and structural compatibility.
JIANBENKJ RV Tank Heater Pad 12″x18″
Type: 12V/13.5V electric holding tank heater pad with built-in thermostat.
Designed for holding tanks up to 50 gallons, this 12″x18″ pad helps prevent frozen fresh, grey, and black water tanks in cold weather. The pad includes an automatic thermostat that turns on at about 45°F and off at about 68°F to conserve energy and protect plumbing.
Application is broad—freshwater, grey water, and black water tanks—and the pad is suitable for RVs, trailers, motorhomes, and marine vessels. Installation typically involves wrapping or adhering the pad to the tank exterior with attention to secure wiring and protected routing.
Buying Guide: Choosing The Right Camper Trailer Heater
Selecting a heater requires balancing heat output, fuel source, installation complexity, safety, and additional needs like plumbing protection. Use the considerations below to match solutions to your trip profile.
Heat Output And Coverage
- BTU Or kW Rating: Match capacity to your camper’s volume. Small trailers can rely on 4,000–9,000 BTU portable units; larger rigs often need 20,000–35,000 BTU furnaces or multi-kW diesel heaters.
- Airflow and Distribution: Built-in furnaces and diesel air heaters push warm air via ducts or vents for even coverage. Portable radiant heaters warm objects directly and may not heat air evenly.
Fuel Type And Power Source
- Propane/Gas Furnaces: Integrate with existing LP systems; efficient for long-term heating but need proper venting and professional installation for safety.
- Diesel Heaters: Run off vehicle diesel tank—good for diesel-powered vans and high-altitude use when automatic altitude adjustment is present.
- 12V Heat Pumps: Offer heating without engine idling and are suited to solar/house-battery systems. Heat pumps lose efficiency in extreme cold compared with combustion heaters.
- Portable Propane Heaters: Useful as supplemental heat; ensure indoor-safety certifications and adequate ventilation and detectors.
- Electric Tank Pads: Prevent frozen tanks; minimal power draw with thermostatic control but require accessible 12V power or shore power.
Installation And Maintenance
- Professional Vs DIY: Forced-air furnaces and diesel heaters often require routing fuel lines, exhaust, and ducting—professional installation improves safety and performance.
- Roof Units: Rooftop heat pumps need compatible roof openings and proper sealing to prevent leaks and wind noise.
- Maintenance: Combustion appliances require periodic inspection of heat exchangers, vents, and flame sensors; electric pads need secure mounting and wiring checks.
Safety Considerations
- Carbon Monoxide and CO2: Any fuel-burning heater used indoors demands functioning CO detectors and proper ventilation.
- Tip-Over And O2 Sensors: Portable units should include tip-over and low-oxygen shutoffs.
- Exhaust Routing: Ensure exhaust outlets are clear of flammable materials and directed away from vents and windows.
Cold-Weather Plumbing Protection
- Tank Pads And Insulation: Use holding tank heater pads plus tank and pipe insulation to prevent freezing in sustained sub-freezing conditions.
- Vent Screens And Covers: Protect vent openings from insects and drafts without blocking necessary airflow for combustion appliances.
Control And Convenience
- Thermostats And Modes: Units with multiple modes (quick heat/sleep) and accurate thermostats help manage comfort and conserve fuel or battery.
- Remote/App Control: Preheating via remote or Bluetooth apps increases convenience for departures and cold starts.
Comparison Perspectives
- Energy Efficiency: 12V heat pumps and well-designed heat exchangers reduce ongoing fuel use; consider battery capacity and solar when boondocking.
- Warm-Up Speed: Combustion furnaces and diesel heaters typically warm a cabin faster than electric heat pumps in very cold weather.
- Operational Cost: Fuel type and consumption vary—diesel and propane costs differ by region; electric systems depend on shore power or battery state.
Use the above criteria to assess which combination of cabin heating, tank protection, and ventilation accessories best fits your camper trailer configuration and typical camping conditions.
