had to buy a mover's dolly to move it around. Would have been better with built-on wheels. Have not tried to use it yet. Initial oil fill would also help had it been supplied. If a fill of gasoline or propane only lasts 8 to 10 hours, it is expensive electricity and will only be used in a real emergency by me and only for long enough to keep freezer and frig cold and furnace running if ComEd has big-time outages. It's insurance, not a convenience.
