Where is obd II or similar port

I have a 2001 national marlin 39ft, with spartan frame, isb 5.9 300hp cummins engine and 6 speed allison trans. The machine has no trip meter of any kind. I would like to add a monitor. I can not find anywere to plug a devise into. Can not find obd II under dash or anywere I can plug something in to read message codes or messages from sensors. Mostly would like fuel milage and how far I travelled on a trip rather than have to calculate it every time.

You won't have a OBD2 Port, yours will probably be a J1708 used in that Vintage Diesels. See Picture for the physical configuration of the mating connector.

The best option for a trip meter is the Scangauge "D"
ScanGaugeD - Advanced J1939 & J1708 compatible Vehicle Monitor for Diesel Pusher Vehicles : Linear Logic

You'll get both a trip comp and a bunch of gauges four at a time.

Look for your diag connector somewhere around the steering wheel column.

Mine didn't have one under the dash but I found one on the engine and ran wires from it to the dashboard.
Good Luck
