Hi David, all of the machines are running similar drive lines, Cummins (option on the DRF, Volvo TAD 1250 standard) Dana, Axletech / Kessler. the Kalmar DRF is slightly different as it uses the Dana TE 32000 gear box (the Linde uses the TE 27000). Service costs should be similar based on the drive line. With regards to parts supply Kalmar has offices in a number of areas of the US and a manufacturing plant in Kansas, as well as one in Ecuador. if you look at the Kalmar web site it will give contact details for the office in Ecuador.
Regards
Ian
