I have seen a few here and there in the tradin times, but none that I know first hand of. Never seen a headache rack on anything but a bucket truck. Just a word of warning though, I work for asplundh and our trucks usually get abused by the guys driving them. Oil changes and lube jobs and filter changes are done on a regular basis where I work, but the thing to remember is that these trucks idle for at least 8 hours a day from fall cold weather till spring warm weather. (we gotta have a place to warm up)
