What is the opinion of Reddit about the
Mr. Heater F242300 MH15C 10,000-15,000 BTU Cooker?

I prefer this one. You can turn it to use it as a stove to (for example) cook fish you just caught.

Check out one of these Mr. Heater combo heater and stoves and consider if you’ve got the space for it. My buddy has one of these, and it kicks off a surprising amount of heat.
