Another vote for the 4dogs, used mine in night temps between 0 and 15 last year on late season elk in AZ and kept my tent plenty warm. Will agree with the stoking tho, got about 4 hours out a couple large pieces of mesquite. Might try the kingsford this year. Mine was only a 12x12 tent an i had their 3 dog model i believe, it was whatever they recommended for that tent size. Heavy and kind of pricey but well made.
