Coolant drain on 2015 DS 4369

[Buly]

Just got my coolant test strips. They want you to drain a sample in a cup, but not from overflow or expansion tank.
So looks like I have to find a petcock somewhere to drain a sample.
Before I start crawling under the coach, does someone know where I can find a spot to drain a sample?
Thanks

Sorry I'm not the most qualified here to answer your question. I have always tested from the overflow tank & called it good so I am also interested in hearing how much more difficult this will be.

I took my sample from a petcock close to where the oil filter is located on my Cummins engine.

Thank you. That narrows it down. Will look for it under the coach.

Look for a petcock on the bottom of the radiator at the back of the rig. That's where it was on our '02 DSDP on Spartan chassis.
