HJ,
I know of several winter tents with scorch marks from an XGK (some of the stoves were mine :0 ). A good stove and my most used for field work (probably because I can use avgas in it). I am now using my second, an EX. Missed the II because my original worked for years till an airline baggage handler crushed it (airline damage cost me my 123 also).
Looks like I should be on the lookout for a used xtreme.
Thanks again,
Jerry
