Welcome to the forum! No real problems with 6200. Some of the first year, early serial numbers had a couple of issues, but all should have been taken care of by now. Improvement kits were installed to correct the problems. Can't remember all the details, but engine mounts were updated, A/C ducts were modified, hydraulic reservoir was added to the hydraulic pump, and maybe a couple of other things. Your dealer should be able to check history on it for you to see if updates were done. If not, pm me with your serial number and I can check for you. Good Luck!
