Seams to me that there are at least a couple of posters whom have never been on the platform of a fueler or an Engineering scissor lift.
Fueler: platform at rear, remote from power source, has a remote dead man switching system, has step access at all raised heights, has fire extinguisher on board.
Scissor lift: drive system below platform, short step access only when retracted, emergency stop buttons, limited foot print stability.
There are no doubt more points, but I just wanted to share in brief my own experience and knowledge.
