Using Honda E2000 to live (winter) in my trailer

I just purchased a E2000 Honda Generator to heat my trailer with a block heater when I am at work. I was thinking about this for some time as to alternative energy source to keep my trailer warm in the dead of winter while I am working. Last year I had food freeze on me and had this long a time to think about this problem. I will also be adding an extra tank for fuel to keep it running at all times. I also have a LP heater mounted on a wall but that will over heat the trailer in 5 minutes time. So that I could only use that a little at a time. I needed something to just keep it warm until I get home.
