When you buy a towable RV, motorized RV, specialty RV or a park model RV, they don’t always come with a generator or you may be replacing a defective or old generator. Many people solve this problem with a portable option, which can work if you don’t have a lot of devices to run. However, you’ll start to have problems when your power needs are constant, like when you want to run a refrigerator and an AC unit. Also, lifting a portable generator that’s large enough for these tasks and moving it away from your belongings so it can safely be operated is back-breaking work, too. And that doesn’t even include all the fuel you have to bring to keep it running.

This is why a lot of RV owners are switching to Cummins Onan installed generators. They’re designed to maximize efficiency in a small footprint and run as quietly as possible. Installed generators generally have on-board tanks that are bigger than what you’ll find on portables, which means they run much longer, too.

Before buying, it’s best to start by determining what size generator you need. Cummins Onan provides an online resource to help make your calculations: https://cumminspowerdocs.com/RV-sizing. When you click the link, you’ll just need to select what kind of vehicle you’ll be using and pick what devices you’ll be powering. When you’re done, the site provides recommendations for what generator types and models work best for your needs.

Cummins Onan RV generators are divided into two basic categories: Quiet Gas (QG) and Quiet Diesel (QD). The letters are used in the name of each model, so it’s easy to see which kind you’re looking at. The QG units run on Liquid Propane (LP) gas, but gasoline-powered units are available as well.
