The open frame unit measures 19.7 x 16.5 x 16.4 inches and weighs 74.3lbs so it’s a hefty machine without being too bulky to fit into a standard RV.

According to customers, the best feature of the Generac is the power in which it started up and continued to run, especially for something so quiet.

The average start-up capacity was 3500W with a running capacity of 3000W so you can use it for things like air conditioners up to 15,000 BTU, as well as televisions and microwaves, without it ever breaking a sweat.

However, it did have some drawbacks, mainly to do with accessing things like the spark plug and outlets. Some people mentioned having to push a little harder the first few times to get it loosened up, so while it won’t affect how you use the Generac, it does mean a little more elbow grease at first.

The weight of this generator is worth mentioning also, and it’s not the best for portability because of its heaviness, so keep this in mind.
