I've driven forklifts all throughout my life, all sizes, from measly little 4k electrics to massive 20ton 4X4's. I liked driving them.... dang good at it too. Just doesn't pay much in most places, the last place I drove for was a tank (lp,water,gas,air) factory.
The made 3,000 gal. lp tanks all the way down to 12.5oz. nox tanks.  Talk about fun....however I did once glance left at some tanks that were leaning in a stack, and before I could look forward again I hit another fork lift coming the other direction.
Bent the fork really bad.... we were both belted in, so nothing happened, except the boss got p.o'd
