Now is not the time to be thinking of that!
Little story, when i was in diesel mechanics school there were a couple of guys (young hotshots) about 1 1/2 years ahead of me that were in their last year at school, then got jobs , they were working for an equipment dealer and had to send some equipment to Alaska, were talking stuff like cat's and dozers ect.. not shure what it was but they neglected to check the antifreeze in a couple big ticket items, and needless to say when they got to Alaska they had cracked blocks. Also needless to say both got fired on the spot...
