Definitely not ultralight camping at all. LOL

I was reading through some old posts and thought I'd drop my 2¢ worth.

If you're going to use a sole cooking solution I'd go with the above link for the 65,000 BTU burner and use a 4.25 or 11 pound (both are 9.3"dia × 12"h) propane cylinder instead of the standard grill cylinder. They would operate the 65K BTU burner for 1.41 to 3.66 hours and take up a fairly small amount of space. Combined with the 12"×12'×2½" it might be a viable option.
