OK where is this truck and why do not post a picture or video of it in action? It does not exist

Did you approach Hyster/Yale with your world beating idea only to be told to get lost?

You make it sound like a idiot can work on this thing I know of a similar idea that was tried out about 20 years ago and it did not work, Some of the techs i see now really do not have a clue unless it is displayed in great detail on their laptops. I got so annoyed at one tech i took his laptop and placed it on the truck there was an issue with and told him have his laptop fix the thing It just sat there.
