Properly understanding your RV's power requirements is essential before selecting a generator. Many RVers make the mistake of buying too small a generator, only to find it can't handle their air conditioner or other essential appliances.
Your RV's power needs depend on several factors: the size of your RV, the appliances you want to run, and whether you'll be running multiple items simultaneously. A small travel trailer with basic appliances might need only 2000 watts, while a large Class A motorhome with multiple air conditioners could require 4000 watts or more.
The biggest mistake I see RVers make is underestimating startup surge power. Appliances like air conditioners can require 2-3 times their running wattage just to start. This is why many 2000-watt generators struggle with 13,500 BTU air conditioners despite the AC's rated power being well within the generator's capacity.
Based on my experience helping fellow RVers calculate their needs, here's a general guide: small travel trailers typically need 2000-3000 watts, mid-sized fifth wheels require 3000-4000 watts, and large Class A motorhomes may need 4000+ watts if running multiple air conditioners.
Before purchasing any generator, I recommend making a list of all appliances you might run simultaneously and noting both their running and starting wattage requirements. This ensures you'll have enough power for everything you need without overloading your generator.
Choosing the right inverter generator for your RV involves balancing multiple factors beyond just power output. After testing dozens of models and speaking with hundreds of RV owners, I've identified the key considerations that truly matter on the road.
Before shopping for a generator, create a detailed inventory of all appliances you might run simultaneously. List both running watts and starting surge watts for each item. Remember that items with motors (air conditioners, refrigerators, microwaves) often require 2-3 times their running wattage just to start.
For RV air conditioners specifically, most 13,500 BTU units need approximately 2400-2800 starting watts and 1200-1500 running watts. This is why many 2000-watt generators struggle with AC units despite the running wattage being within capacity. Consider installing a soft starter if you plan to run an AC with a smaller generator.
Add up the total starting wattage of all appliances that might start simultaneously, then add a 20% buffer for altitude and temperature variations. This gives you your minimum required generator size.
Generator noise is one of the fastest ways to make enemies at a campground. Many campgrounds have strict noise restrictions, often limiting generator operation to specific hours and requiring noise levels below 60-65 decibels.
Look for generators rated at 65 decibels or less when measured from 23 feet away. Premium models like the Westinghouse units operate at just 52 decibels - quieter than normal conversation. These ultra-quiet generators allow you to run power overnight without disturbing neighbors.
Remember that noise levels increase under load. A generator rated at 60 decibels at 25% load might be significantly louder when running your air conditioner at full capacity. Consider testing noise levels at various loads before purchasing if possible.
Weight and dimensions matter significantly in RV applications. Measure your available storage compartments before purchasing - many RVers buy generators that don't fit in their designated storage space.
For frequent travelers, generators under 50 pounds are much easier to move around campsites. Heavier models should have built-in wheels and handles, but remember you'll still need to lift them in and out of storage compartments.
Consider how you'll secure the generator for transport and theft prevention at campsites. Many RVers use cable locks through the generator frame or mount them in dedicated compartments with ventilation.
Carbon monoxide safety is non-negotiable with generators. Never run a generator inside your RV, under awnings, or in compartments that communicate with living spaces. CO detectors are essential - install multiple detectors and test them regularly.
Maintain at least 10-15 feet of distance between your generator and your RV, with the exhaust pointing away from doors and windows. In windy conditions, you may need even more distance to prevent exhaust from entering your RV.
Modern generators with CO Shield technology provide an extra layer of protection by automatically shutting down if dangerous CO levels are detected. This feature is worth the extra cost for the peace of mind it provides.
Gasoline generators offer maximum power output and fuel availability, while propane generators run cleaner and store fuel indefinitely without degradation. Dual fuel models offer the flexibility to choose based on availability and preference.
Consider your typical camping style when choosing fuel type. For extended boondocking trips, propane's infinite storage life might be advantageous. For frequent weekend camping, gasoline's availability and higher power output might be preferable.
Runtime per tank is crucial for overnight operation. Look for generators that can run at least 8-10 hours at 25% load on a single tank. This ensures you won't need to refuel in the middle of the night.
After extensive testing and real-world use with various RV types, the Westinghouse iGen2550 remains my top recommendation for most RVers due to its exceptional balance of quiet operation, reliable performance, and reasonable price point.
For those needing more power for larger RVs or multiple air conditioners, the Champion 4000W offers the best power-to-weight ratio in its class. Budget-conscious buyers will find excellent value in the Redact 2400W without sacrificing essential features.
Remember that generator safety should always be your top priority. Invest in quality CO detectors, maintain proper distances, and never cut corners on ventilation. No amount of convenience is worth risking your health.
Whichever generator you choose, proper maintenance and careful operation will ensure it provides reliable power for years of RV adventures. Happy camping, and may your generator always start on the first pull!
