1999 Utility Reefer Trailer 53'x102". Spring ride suspension with low pro 22.5 tires and hub piloted wheels. Has Thermo King Whisper SBIII unit on it with a Yanmar Motor. Motor runs very well but the unit DOES NOT cool. Thinking it is out of freon. Showing 16,150 hours of total engine run time. We used the unit to store our own wheat seed. Now that we are not saving our own seed anymore, we have no need for it anymore. Thanks for looking and contact me with any questions.
