just a couple questions
- an E6000I? (actually theres no such thing as an E6000I, its just E6000), or a GC25K? there is a big difference between the two trucks.(one is electric and the other is gas/lpg powered). hmmm.....

- can you look on the dataplate and get the complete model and serial number and come back with that?
- How many hours are on the truck?

can't help you unless we know which truck it is
;o)
