i think every tech is biased to the brand that he is most familiar with. i have 30 years in the lift truck bsns and have seen quite an evolution in the peripherals but as dave said, lift trucks aint changed a whole lot in the last 30 years except to get more complicated. that said some are less labor intensive than others. i have seen a toyota 4y engine in a 7 series truck removed in 57 minutes. i have also seen a head gasket replaced (no milling) in 45 minutes. i know i am biased but if they're all going to be complicated to repair an old fart like me will opt for the easy to access any time.
