My wife wants to get rid of our old propane Coleman camp stove. Its 18 years old and has seen better days. We were looking at the camp chef Teton or maybe the Everest. The main difference seems to be the BTU's. Teton at 10,000 per burner, and Teton at 20,000 per burner. Is the 20,00 really needed? And by the way, why does no one put levelers on camp stoves? Hate having my eggs slide to one end.
