The 2-gallon tank with a fuel gauge helps monitor levels during trips, contributing to better planning for horse trailer needs.
Best for: Trailer users who want a compact, affordable option with reliable run time and RV compatibility. Choose this if you prefer straightforward operation and 14-hour endurance at light loads.
Caution: The smaller fuel tank means longer trips require more frequent refueling stops, especially at higher power draws.
Westinghouse 12500 Watt Dual Fuel
With 12500 peak watts and 9500 running watts on gasoline, and 11200 peak with 8500 running watts on propane, this model supports heavy trailer setups and substantial backup needs. It features remote electric start, a six-gallon fuel tank with gauge, and multiple outlets, including RV-ready and transfer-switch-ready options. The VFT display provides real-time voltage, frequency, and hour data, aiding precise load management.
Best for: Heavy-duty trailer setups or remote work sites where high power is required and transfer switch readiness is important. Choose this if you need serious peak capability and multiple safety features.
Caution: Higher output means greater weight and potential noise; assess transport and noise considerations for campgrounds or quiet zones.
Westinghouse 4650 Peak Watt Dual Fuel
This compact dual-fuel option provides 4650 peak watts and 3600 rated watts on gasoline, with propane output at 4650 peak and 3240 rated. Its four-gallon fuel tank supports extended use, and it includes essential outlets: a standard 120V duplex, an RV-ready TT-30R, and a 4-outlet configuration with rubber outlet covers for safety. It’s designed to be easy to start and operate for trailer enthusiasts who need dependable backup power.
Best for: Trailer users seeking a balanced, portable generator with several receptacle options and built-in safety features like a CO sensor. Choose this if you want a mid-size unit that handles multiple trailer appliances without overkill.
Caution: Propane performance can vary with temperature and altitude; have gasoline as a backup if you operate in harsh conditions.
Buying Guide
What to consider when choosing a generator for a horse trailer
- Power needs: Estimate total wattage for lights, vent fans, water pumps, and any appliances you plan to run. A model in the 3000–6000 running watts range often covers basic trailer needs; 8000+ running watts suits larger loads or EV charging prep.
- Fuel type and capacity: Gasoline units are common and quick to refuel, but dual-fuel options offer propane compatibility for longer trips or supply chain concerns.
- RV readiness and outlets: Ensure at least one 30A RV outlet and appropriate 120V outlets. Consider TT-30R or L14-30R configurations depending on trailer and transfer-switch plans.
- Safety features: Look for CO sensors, automatic shutdown, oil shutdown, and rubber outlet covers to protect against moisture and debris.
- Run time and fuel gauge: Longer runtimes reduce refueling frequency during trips; built-in fuel gauges help plan usage and avoid running dry.
- Portability: Weight, handle design, and wheels affect transportability from truck to trailer. Inverter models generally offer cleaner power and quieter operation.
- Noise and emissions: Inverter generators tend to run quieter and with cleaner emission profiles, which is important at campgrounds or near stables.
Frequently Asked Questions
- What size generator do I need for a horse trailer? — It depends on your load. For basic lights, fans, and pumps, a 3000–5000 running watt inverter can suffice; for larger trailers with more electronics or climate control, 6000–9000 running watts is more appropriate.
- Is an inverter generator better for trailers? — Yes, inverter models provide cleaner power suitable for sensitive electronics and tend to run more quietly and efficiently.
- Do I need dual-fuel capability for trailers? — Dual-fuel can be beneficial for extended trips where propane is more readily available or cheaper than gasoline.
- What about safety features? — Look for CO sensors, automatic shutdown, low oil shutdown, and proper outlet safety covers.
- Should I choose remote start or electric start? — Remote or electric start adds convenience, especially for cold mornings or when you need quick access to power.
- Are transfer switches necessary for trailers? — Transfers switches are essential if your setup includes a home backup system or if you want to switch between utility power and generator without backfeeding.
