RV Generator Buyer's Guide

How to Pick the Perfect RV Generator

By  | Generator Product Expert

Whether you travel in your RV to spend more quality time with family and friends or to escape from it all, you will need a reliable source of power for your travels.

RV generators are specifically made for powering RV appliances and accessories.

RV generators are more expensive than portable generators. While this can be an expensive investment, having constant power, day or night, is worth the cost to most.

Select a Fuel
RV generators come in different styles designed to run on different types of fuel. Make sure you select the one that's most compatible with your RV and that will meet your personal travel expectations.

If you are replacing an existing RV generator you will need to know what fuel type you currently have. Also be sure to take measurements in the generator compartment of your RV to make sure you select one that will fit.

Diesel RV GeneratorDiesel
If your RV runs on diesel, then it's best to have a generator that also runs on diesel. With a diesel generator, you can utilize one fuel source for both your RV and your generator.

Diesel also produces more power than propane. It's cleaner burning than gasoline, non-explosive, and safer to store.

Liquid Propane RV GeneratorLiquid Propane
Liquid propane is an environmentally-friendly fuel choice with cleaner emissions, and a longer shelf life.

The downsides, however, are that the run time is limited to the size of your propane tank and the power output tends to be reduced by around 10% compared to gas or diesel.

Gasoline RV GeneratorGasoline
Some people prefer gasoline-powered RV generators because the fuel is easy to find and less expensive.

The downsides, however, are that they're highly flammable, their fuel has a shorter shelf life, and they burn through fuel much more quickly than a diesel.

Commercial Mobile Generators
Commercial RV GeneratorIs an RV generator lacking in power for what you need? If it's going to be used on a regular basis for extended amounts of time, you may want to step up to a commercial model. Commercial mobile generators are the ones you rely on for commercial and large-scale emergency services. They're rugged and designed for the toughest of conditions.

These are the mobile generators used by telecom workers who repair the power lines, they're the generators used for emergency response vehicles that need to provide lighting, communications, and medical care on the spot.

A popular use today for commercial mobile generators is powering food trucks. Food trucks are rapidly growing in popularity, offering the ability to reach a wider market with less overhead costs than a brick-and-mortar location, and these generators offer reliable power for all of your on-board appliances day after day.

If you're looking for serious power that you can rely on for the biggest and toughest of jobs, then commercial mobile generators are exactly what you need.

Gas RV Generators MUST Comply With EPA's EVAP Regulations
According to the Environmental Protection Agency (EPA), gas fumes produced inside the tanks of RV generators must be captured and returned to be burned. This has lead to the manufacturing of EVAP generators that are specially designed to meet these regulations.

Typically, motorized RVs already have a built-in system that complies with these regulations, but most tow-behinds don't. The towable RVs require that you install an EVAP generator, certified hose, special fittings, a specially designed metal tank, and a carbon canister. If your system is missing any one of these certified EVAP components, you'll be subject to a hefty fine should you get stopped and inspected.

So unless your gas RV generator pulls its fuel from the chassis fuel tank, you'll want to be sure you're compliant on the roadway so you don't get stuck with a major fine. Shop EVAP RV Generators.
