I have one and use it on occasion. For a while, it was ALL I had and kept me flying through the winters for years as I base OUTSIDE...especially during BOMB CYCLONE years!
Very good...nice piece of kit!
I connected all the elements and attached them to a trolly so we could move it around easier with the propane tank, etc.
It's a good heater and effective even down to 0-10 degrees F.
