It says 'Warm Morning Catalytic' on the front of it. By the looks of it, I would guess it's original. It and the stove is hooked up to a propane tank under the drivers side.
The previous owner told me he's used the stove and heater, but propane makes me a little nervous. The tank seems to be 75% full, and I'd really like to have it tested before I used it. For now I just need to figure out if I can get rid of the pipe.
Thanks for the replies.
