OBD II was standardized in 1996, everything built onward has OBDII. Everything (with just a couple exceptions) before 1994 is OBD I.
The location should be below the dash and somewhere adjacent to the driver's position. I've seen them hidden by plastic flaps and also positioned above the transmission hump. Most are to the left of the driver's position as this makes logistical sense for wiring location in most vehicles.
OBD readers are available at any autoparts store.
Some earlier GM vehicles had a code sequence port, don't know if it applies to your coach, probably not.
