the contractor I used to work for had a tower erection and maintenance side. A couple of the guys had erected and climbed 1500+' towers. One guy drove non-stop to Arizona once from Kansas to climb a 1700' tower to replace a lightbulb, then drove home.
They told tales of how they used to make extra money buy renting a car when they got to the site, living in it while working. They'd take off the wheel and attach a rig they'd made to use the car as the winch for lifting parts and tools to the top of the towers.
