After reading all of the great advice I recognize that the 48v would be a great machine. However, we are most concerned with maneuverability with this unit. The 48V is a larger machine. Plus we have never had an issue with speed, probably since we are only a 35,000SQF warehouse with a lot of machinery and inventory.
I believe it is all going to come down to the warranty and service at this point. Down to the clark and mitsubihis 3 wheel 36v units.
