Re: The last 3ft (mast work)
I've seen where just two equal-level mast steps have been installed 4-5 feet below the truck so that the person up there has real solid footing and a good height to work on things at the masthead..
Avoids the run of steps all along the mast, and puts less load on the chair, lines, etc once you're 'up there'.. a telephone linesman's waist strap will improve the setup even more..
