I am betting that any decisions made that might allow that to happen would only be made if the number of forklifts purchased reached into the "thousands".
And even if it did ever occur, surely there would be a lot of restrictions on just what the "out of dealer/corporate network" personnel would have access to, etc.
A more likely scenario (in my opinion) would be that the purchasing company would negotiate some kind of deal or agreement wherein OEM factory service reps or techs from the OEM local dealership would come onsite to perform services or adjustments and such.
Of course, if a local dealer was big enough to shoulder the risks of letting proprietary software/hardware be pilfered in a process like that, I guess they could shrug it off.
And then there is also the possibility that policies exist PROHIBITING dealers from engaging in activities like this.
I really can't imagine an OEM willing to give away intellectual property that they have vested huge sums of capital in, and for which they expect to make a profit from having said intellectual property in their possession.
I am, of course, curious to learn what prompted this discussion, but that may be something you SHOULD NOT reveal.
