I recommend a Yamaha EF3000iseb. I runs at 3000 watts with a boost to 3800 watts when needed. Be sure to look for the model with the boost. I’ve had mine since about 2003 and is used almost every weekend at the track. Changed the plug once, a couple of oil changes and a new air filter in 12 plus years. Also had to buy two batteries (electric start) over the years. Just bought my second battery today. And is quiet to boot. Only other generator I would own is a Honda 3000.
