How to Choose the Right RV Generator for Your Needs

Whether you’re dry camping in the wilderness or backing up your power at a campground, the right generator can make or break your RV experience. Understanding how to choose the right RV generator for your needs ensures you stay powered up, comfortable, and safe—no matter where your travels take you.

Why Your RV Generator Choice Matters

RV generators provide power when shore power isn’t available, running essentials like:

  • Air conditioners
  • Microwaves and appliances
  • TVs and electronics
  • Water pumps and heaters

Choosing the wrong size or type of generator can lead to overloaded circuits, noisy nights, and even damage to your RV systems. If you’re not sure what fits your setup, Daisy RV can help match you with the right power source.

Types of RV Generators

1. Portable Generators

  • Freestanding units you place outside your RV
  • Typically run on gasoline, propane, or dual-fuel
  • Easy to maintain and replace
  • Ideal for part-time RVers and smaller rigs

2. Built-In Generators

  • Permanently mounted into your RV’s chassis
  • Usually powered by your RV’s fuel system or propane
  • Start with the flip of a switch inside the RV
  • Best for larger RVs or full-time use

Key Factors When Choosing an RV Generator

1. Power Output (Wattage)

  • Add up the wattage of everything you plan to run at once
  • Most RV A/C units need 1,500–3,000 watts to start
  • Look for starting watts and running watts on generator specs
  • For 30-amp RVs: 3,000–4,000 watts is typically enough
  • For 50-amp RVs: 5,500–7,000+ watts may be needed

2. Fuel Type

  • Gasoline: Easy to find, but doesn’t store well
  • Propane: Cleaner burning, easy to store, but may need adapters
  • Diesel: Best for diesel motorhomes
  • Dual-Fuel: Flexible option for different scenarios

3. Noise Level

  • Measured in decibels (dB) — lower is quieter
  • Look for generators under 60 dB for campground-friendly use
  • Inverter generators are usually the quietest option

4. Portability and Weight

  • Consider where and how you’ll store the generator
  • Some models come with wheels and handles
  • Check if you need a lift or mounting bracket

5. Inverter vs Conventional

  • Inverter generators produce cleaner power for electronics
  • More efficient, quieter, and safer for TVs, laptops, and phones
  • Conventional units are louder but often cheaper at higher wattages

Tips for Safe Generator Use

  • Never run a generator indoors or in an enclosed space
  • Use CO detectors inside your RV
  • Keep the generator at least 5–10 feet away from doors and windows
  • Follow proper break-in procedures before full use
  • Regularly check oil and filters
