Most important piece of equipment to work my firewood? No question...My truck. If my saw breaks, no worries, I have 27 more. If my splitter won't start...meh...I can get by doing something else productive or I can swing a maul. If my trailer burns up a bearing I can get by for a while just tossing into the bed of my truck. But...gheeze...when my truck breaks down, EVERYTHING comes to a screeching halt. I mean EVERYTHING. Certainly every tool we have plays a part in our entire operation, and they are all important. But, at least for me, my truck is the MOST important. The only one I have, only one I can afford. Today I burnt up another coil pack and decided to check out a clunking noise from the front end...ugh...ball joint. These are nothing I can defer until a rainy day and they got to be fixed now... which means no cutting, splitting, lugging, and stacking today. God bless the trucks!
