Those were exactly my observations as well regarding the Camp Chef Mountaineer. I too have looked at the bags from Blue Ridge and would invest in one should I purchase the Partner stove. I also like the lower burner BTU output of the Partner compared to the Camp Chef, i.e., 10,000 vs 20,000 per burner respectively. Less BTU I would assume means less consumption and at 10,000 BTU I wouldn't imagine there would be any real "time to boil" difference compared to 20,000 BTUs, for the typical needs of using a 1 or 2 quart pot. I won't be making dinner for 10 guests.
Those adjustable feet certainly would be a good addition, so many surfaces used for a stove are uneven. However, I was hoping to shop around and get a bit of a better deal than offered directly from the manufacturer, a trade off it seems.
