I hated those things - they were a maintenance nightmare but they did serve admirably since WW II. When they work they worked great. The burner units typically used with the field range could bake, fry, simmer - you name it; an example of American ingenuity, but they were time consuming to maintain requiring scrupulous cleaning and not always available repair parts. mmm... fresh baked cookies...
I'm having flashbacks to Command Logistic Review Team inspections... (shudder).
The unit could also be used with the old field autoclave for sterilizing instruments for field medical units in the Army, Navy, and Marine Corps. They had a nasty reputation, too; we used to berm them in especially in dynamic, asymmetric threat environments but then we had ample amounts of sand available.
To use it camping though? Only if I deployed with a reinforced rifle Company of my closest friends...
Sounds like you just have the M2 burner unit though. If you also have the Field Range and employ it the way STN suggests with a modern propane burner -- now you're talking.
