ewilkie,
The Yamaha EF3000ise (without the power boost) will operate all 110V items (with the exception of the water heater) at the same time, in our 17'
Casita. We usually operate it in the power saver mode. The
generator slows momentarily during the A/C start cycle. When I was running a test, the interior
lights, Fantastic Fan, bathroom fan, stove vent fan, water pump, Coleman Mach A/C, and
microwave were all operating. We purchased that
generator to also provide an emergency source of power at home.
Our Yamaha was also converted to use
propane fuel since it sits behind the existing
propane tanks, eliminating the need to carry gasoline and its maintenance issues.
No problems in 2 years of use.
