Per Diem for Separation PPM?

I’ve been looking through so many threads, even in the JTR, but I can’t seem to find whether or not I’ll get per diem for my final ppm. What I’ve read is that it’s based on the allotted travel days, but I’ve also seen every 350 miles = 1 Day.

My separation orders explicitly state I have “0” travel days. If that’s the case, would I fall into the 350 miles = 1 Day bucket? I just don’t want to spend carelessly. I could probably get away with sleeping at rest stops if it means saving a bit of money before my last check; but I’d much rather be well rested for the long haul.

Any direction would be greatly appreciated!
