Thanks for the pics and info on everything so far!

Mostly pretty steady. Around 36-38 psi operating about 1500rpm. Around 18-20 psi at idle (720 rpm). Cold starts would be about 40psi at idle up to 60psi only if I tried to drive before it warmed up above 150F. There were occasional fluctuations, but never more then 2-3 psi and usually coincided with high or low ambient temps, or a long pull up a grade. Don't remember seeing it drop below 18 at idle.

Pulling a grade, recently, I started to notice the pressure slowly drop to around 32 psi, then return to normal after I got back toward level ground. But that was only in the last week or so before I parked it for an oil change and overhead adjustment. Went about 17k on that oil adding a gallon every 3k. So, not sure how the oil life played into what I was seeing there.
