Choosing the right dual fuel generator for your travel trailer starts with matching real power needs to portable performance. A reliable generator keeps lights on, refrigerators cold, and devices charged—even in remote camping spots. Dual fuel models add flexibility by running on either gasoline or propane, so you’re never stranded when one fuel type is unavailable. Westinghouse leads this space with proven inverter and conventional units tailored for RV life.
Why Dual Fuel Matters for Travel Trailers
Dual fuel generators solve one of the biggest challenges RVers face: fuel availability across regions. Gasoline is easy to find at roadside stations, while propane is standard at most campgrounds. Switching between the two means fewer supply chain worries during cross-country trips. Additionally, propane burns cleaner than gasoline, producing less carbon monoxide and requiring less frequent oil changes. In practice, many users run on propane during extended stays at campgrounds and switch to gasoline when heading off-grid.

Choosing the Right Size Generator for Your Travel Trailer
Selecting adequate wattage prevents frustrating brownouts and breaker trips mid-trip. Start by calculating total simultaneous wattage draw from every device you expect to operate at once. Add 20–25% buffer above calculated needs to accommodate unexpected surges—especially motor-driven appliances like refrigerators and air conditioners.
Estimating Load Requirements
Example load calculation for average travel trailer setup:
| Appliance | Running Watts | Surge Watts |
|---|---|---|
| LED Lights | 50W | 50W |
| Refrigerator | 200W | 1,200W |
| Microwave | 1,000W | 1,500W |
| Roof AC (Small Unit) | 1,500W | 3,000W |
| Laptop Charging | 60W | 60W |
| Phone Charging | 10W | 10W |
| Total | 2,820W | 4,820W |
Based on this math, a 4650-peak-watt generator comfortably meets needs with headroom. Larger units with 5000+ watt capacity allow future upgrades or additional appliance usage without overloading circuits.
Pro tip: Keep a spreadsheet log tracking actual power draw during trips—that data becomes invaluable when upgrading or replacing equipment later.
Fuel Types Compared: Gasoline vs Propane
Each fuel brings distinct advantages depending on usage patterns and travel habits.
Gasoline Advantages:
- Widely available at nearly every gas station nationwide
- Higher energy density yields more power per gallon
- Lower upfront conversion costs for compatible generators
Gasoline also starts quickly after sitting unused for weeks, unlike some older propane systems prone to vapor lock issues in cold weather.
However, ethanol-blended fuels degrade faster, forming varnish deposits inside carburetors unless treated with stabilizers regularly. Most experienced RVers rotate fuel every 30–60 days or install fuelless EFI systems in newer units.
Propane Perks:
- Indefinite shelf life eliminates spoilage concerns
- Burns cleaner—no oil mixing or injector deposits
- Refill infrastructure exists at virtually every campground
Despite slightly lower BTU output, propane often extends runtime significantly when paired with high-efficiency inverter generators. Users camping remotely appreciate not having to manage smelly gasoline containers or worry about fire hazards associated with volatile petroleum vapors.
