Boondocking on the way out here, I ran my toaster - 750w, coffee maker - 650w and tried to run my microwave - 1500w, (950w output). I hit start on the mw and as soon as it kicked in, the generator stumbled and went out like a light.
If you add it all up, it's only 2850w. The Onan is supposed to support 4k. What am I missing?
