Can't tell by your signature in this forum the year coach, or engine, but we have an 8V82 Detroit Diesel that is pre computer. The prior owner, Todd Fickema added a DIGI-PANEL. I really like it. We use it along with the original gauges that are known the be slow to respond and inaccurate at best. The the DIGI-PANEL reads coolant temp, trans temp, oil pressure and battery voltage, has adjustable high and low limits with an audible alarm.  It give us some additional security.

I think you will find that these coaches do not respond like a conventional vehicle to overheating. When pulling a long steep  grade with high ambient temps, if we pull off the highway and let it idle at approx 1000 rpm min, the temp will drop 20 degrees or more in about ten minutes. Heavy traffic at low speed actually results in a dramatic temp drop after running on the expressway at cruising speed.

Your new coach is beautiful! Nothing like a "trial by fire trip" to get you used to your coach.   You will get lots of compliments on that one. Not far from Tom's area in Arizona at a border check point, the officer just wanted us to hold up so that he could tell us  'that thing is bad a**.
Can't wait to see your improvements.  Enjoy !
