champion 100263 3400 watt inverter/generator question

Been using the Champion 3100 inverter generator for 3 years now. Average between 60-80 hours per year. Change oil every 50 hours. Have had absolutely no problems and starts on the first or second pull everytime. No complaints about noise from anyone. It has handled 100+ heat in the shade and also elevations up to 9000 ft or so. Rides in the back of my truck.

Not downing the red, blue, or any other colored generators. Just my experience with the yellow one.
