I bought these over the CAT units because they were a hair cheaper and had USA engines, and at that, proven engines where all of the skids, 4 and 5 cylinders, are essentially the same maintenance wise.
No more USA engines- all SSLs and CTLs will now use either a 3.1L or 3.3L four cyl Yanmar engine.
