3400 Watt generator, uses Gas and Propane to run. Less than 100 hours on it. Moved, sold my RV and don't need. Works great. FYI - I have one star because an offer up user wanted to back out of an already shipped sale by giving an obviously bogus reason. Offer up sided with me during the dispute but not before she was able to give me a bad review. I have perfect reviews on ebay and have used Craigslist for years without any complaints.
