I burn a lot of cottonwood. Just split it thick. Sometimes maybe I can just put four pieces and fill some gaps with small rounds from the branches.I've actually burned a lot of cottonwood in the BK and it does really well. The ash helps and it makes a lot of ash. You've got to dry it out of course. It also takes a lot of work to process that heavy green wood and you need a lot more of it to match the #s you get from fir. I'd prefer our cottonwood to western red cedar.
Some places in this nation, all they have to burn is cottonwood and those folks stay warm just fine.
Congratulations on the new truck. I have a 2000 F350 diesel which has been the subject of a huge crime wave in our area. People are getting them stolen so much I'm afraid to leave it at the trailhead. They must be really easy to steal.
That is still giving me a 24hrs schedule with lots of coals in the ashes for reloads. I learned to split big the kind of wood I get around here. That makes the trick. It is a pain to process it, more when green. Too much moisture. What I do is cut in rounds and leave it there for months before split it. That helps a lot. Just have to face the twisting and knots when splitting it.
The reason why I went with a 40 tons splitter. Lol.
40 ton splitter don't care how twisted it is. It pops it open like nothing and .more if you let it dry for awhile first like I do.
