Well as an independent you would probably not have the support for the Lindi or Jungheinrich as they require a laptop and programing. Crown in my opinion makes a terrible 3 wheeler.
The Mitsi and Cat are the same truck for the most part and both seem to stand up very well in the A/C version, the D/C versions were also pretty good but did go through the odd transistor(not a huge cost or a difficult repair.
Toyota had some bad gear boxes and the masts were not great from the ones I serviced the electronics were quite good though with only minor repairs ever required.
Hope that helps.
