Spartan says the hydraulic oil does not need to be changed unless it is contaminated by something, only the filters (item 1g) require regular maintenance changes. The hydrauliclly-driven fan motor required no regular maintenance.
Their maintenance schedule is designed for full-time use, not RV's, so IMO it is OK to double their maintenance schedule intervals.

You likely have the Spartan K2 chassis, however the maintenance should be the same.
