Hi Ford truck guy.. It's a "Fire Dancer". I got it around 10+ years ago and is a nice compact unit. The lid you see in my pic screws on like an old air cleaner would on an old V8 with a carb on it and you can haul it around easily.
It has it's own regulator and valve. You can set it really low or full on. Throws off some good heat too, so even under the awning, on a chilly night, you get heat from it and lets you stay out a bit longer. Then, when you are ready to retire, just turn it off, pop the lid on and go to bed!
