Why a Generator is Essential for Your Travel Trailer

While RV parks and campgrounds offer shore power hookups, true freedom often lies in boondocking or dry camping—setting up camp in locations without electrical connections. This is where a generator becomes indispensable. It allows you to power:

  • Essential Appliances: Refrigerators, lights, water pumps, and charging your devices (phones, laptops).
  • Comfort Conveniences: Air conditioners (especially crucial in warmer climates), microwaves, coffee makers, and entertainment systems.
  • Medical Equipment: For individuals with specific medical needs that require continuous power, a generator provides a sense of peace of mind.

Without a generator, your off-grid camping experience is limited by your battery bank's capacity, which can quickly deplete, especially with power-hungry appliances.

Understanding Generator Types for Travel Trailers

When it comes to generators for travel trailers, you'll primarily encounter two main types:

1. Conventional (Open-Frame) Generators:

  • Pros: Generally more affordable per watt, often capable of higher power output.
  • Cons: Significantly louder than inverter generators, produce "dirty" power (less stable voltage and frequency), and are less fuel-efficient as they typically run at a constant high RPM. Their open-frame design can also make them bulkier and less protected from the elements.
  • Best for: Heavy-duty applications where noise and clean power aren't primary concerns, like construction sites, or for those on a very tight budget with minimal sensitive electronics.

2. Inverter Generators:

  • Pros:

    1. Quiet Operation: This is a major selling point for RVers. Inverter generators are designed with advanced muffling and often have "Eco-Mode" or "Economy Mode" that adjusts engine speed to the load, significantly reducing noise levels (often 50-60 dB, comparable to a normal conversation). This is crucial for respecting campground noise limits and enjoying peaceful surroundings.
    2. Clean Power: Inverter technology converts raw AC power to DC and then back to clean AC power. This produces a stable sine wave, making them safe for sensitive electronics like laptops, smartphones, and RV appliances with delicate circuitry.
    3. Fuel Efficiency: By adjusting engine speed to meet demand, inverter generators consume less fuel, leading to longer run times per tank and cost savings.
    4. Portability: Typically lighter and more compact than conventional generators of similar wattage, making them easier to transport and store in a travel trailer.
    5. Parallel Capability: Many inverter generators can be linked together with a parallel kit to double their power output, offering flexibility if your power needs change.

  • Cons: Higher initial cost than conventional generators of similar wattage.
  • Best for: Nearly all travel trailer applications, especially for boondocking, camping in noise-sensitive areas, and powering sensitive electronics. They offer the best balance of performance, quietness, and efficiency for RV life.

Key takeaway for US RVers: While conventional generators exist, inverter generators are overwhelmingly recommended for travel trailers due to their quiet operation, clean power, and fuel efficiency – factors highly valued in US campgrounds and national parks.

Sizing Your Travel Trailer Generator: Watts and Amps Explained

Choosing the right size generator is paramount. Too small, and you won't power your essential appliances; too large, and you're wasting money on unnecessary power and fuel. Travel trailers typically use 30-amp or 50-amp electrical systems.

To determine your needs, follow these steps:

  • List Your Appliances: Identify every appliance you plan to run simultaneously.
  • Find Starting and Running Watts: Most appliances have two wattage ratings:

    1. Starting (Surge) Watts: The brief, higher wattage needed when an appliance (especially those with motors like AC units, microwaves, or refrigerators) first kicks on.
    2. Running (Continuous) Watts: The power required to keep the appliance operating.
    3. Pro Tip: Check the appliance labels or owner's manuals for these figures.

  • Calculate Total Running Watts: Add up the running watts of all appliances you want to use simultaneously.
  • Identify Highest Starting Wattage: Determine which single appliance has the highest starting wattage.
  • Determine Required Generator Output:

    1. Your generator's running watts should meet or exceed your total running watts.
    2. Your generator's starting watts should meet or exceed the highest individual starting wattage among your appliances.
    3. General Rule of Thumb for US Travel Trailers:

      • Small Trailers (pop-ups, smaller travel trailers with minimal AC): 2,000 to 3,000 watts are often sufficient for basic needs (lights, charging, small appliances). A 2,200-watt inverter like the Honda EU2200i is a popular choice.
      • Mid-Size Trailers (20-30 ft., 30-amp service, one AC unit): You'll likely need 3,000 to 4,000 watts to comfortably run your AC, microwave, and other amenities. Many 3,500-watt inverter generators fit this bill.
      • Large Trailers (30-40+ ft., 30-amp or 50-amp service, multiple AC units/heavy appliances): These often require 5,000 to 7,500 watts, or even up to 12,000 watts for heavy usage with two ACs and multiple high-draw appliances. For 50-amp RVs, you'll need a generator capable of supplying 240V, or two smaller parallel-capable generators (often two 2,000-watt units in parallel can power a single 13,500 BTU AC, but not usually a 50-amp system completely).

Example Wattage Needs for Common RV Appliances:

  • Air Conditioner (13,500 BTU): Running 1250-1500W, Starting 2750- 3500W.
  • Microwave: Running 1000-1500W, Starting 1000-1500W
  • Coffee Maker: Running 600-850W, Starting 600-850W
  • Refrigerator (RV Type): Running 180W, Starting 600W
  • Hair Dryer: Running 1200-1800W, Starting 1200-1800W
  • Lights (LED): Minimal (e.g., 5-20W per light)
  • Laptop/Phone Charger: Minimal (e.g., 50-100W)

Remember the "20% Rule": It's often recommended to choose a generator with a power output at least 20% higher than your calculated maximum power requirements to avoid overloading and extend the generator's lifespan.

Essential Features for Travel Trailer Generators

Beyond wattage, consider these features for enhanced convenience and functionality:

  • Fuel Type:

    1. Gasoline: Most common, widely available.
    2. Propane (LP): Burns cleaner, stores longer, often preferred by RVers with existing propane tanks.
    3. Dual-Fuel: Offers the flexibility to switch between gasoline and propane, useful for availability and extended run times. Many popular models offer this.
    4. Diesel: Less common for portable travel trailer generators, more typical for large, built-in RV generators.
    5. Solar Generators/Portable Power Stations: While not traditional "generators" in the internal combustion sense, these battery-based systems charged by solar panels are gaining popularity for quiet, emissions-free power. They are excellent for lighter power needs and charging sensitive electronics, but larger models can be expensive and may not fully replace a gas generator for high-draw appliances like AC.

  • Noise Level (Decibels - dB): Look for decibel ratings at various loads (e.g., 1/4 load, rated load). The lower the dB, the quieter the generator. Most quiet inverter generators range from 48dB to 65dB. Many US campgrounds have noise restrictions, so this is a crucial factor.
  • Electric Start/Remote Start: Simplifies starting the generator, especially convenient on cold mornings or in inclement weather.
  • Parallel Capability: Allows you to connect two smaller inverter generators for combined power, providing flexibility for varied power needs.
  • RV-Ready Outlet (TT-30R): A dedicated 30-amp outlet designed for direct connection to your travel trailer's shore power cord.
  • Fuel Gauge/Digital Data Center: Helps you monitor fuel levels, runtime, voltage, and power output.
  • Run Time: How long the generator can run on a single tank of fuel at a given load. Longer run times mean fewer refueling stops.
  • Portability (Weight and Dimensions): Consider how easy it is to lift, carry, and store the generator. Wheels and a sturdy handle are a big plus.
  • Safety Features:

    1. CO Shutoff Sensor (Carbon Monoxide Sensor): Automatically shuts down the generator if dangerous levels of carbon monoxide are detected, a vital safety feature for preventing CO poisoning. Many newer models sold in the US now include this.
    2. Low Oil Shutoff: Protects the engine from damage if oil levels drop too low.
    3. Overload Protection: Prevents damage to the generator and your appliances in case of an overload.
