I have had this generator for a little over 3 months and have about 25 hours of runtime with it. I haven't had any problems with it and it is a well built, solid generator.
Old 6500w generator was getting old didn't have enough power for the electric water heater. Got the 9500DF to power whole house and keeping the old generator as a spare. We normally loose power once a year 5 - 8 days. Dual fuel allows me to use Propane tanks from the bbq if gas is hard to find.
