Im set to buy a 2001 coach , cummins 8.1 isc, 26,000 miles. Should i be concerned because it hasnt been driven enough ?

Advice from both Caterpillar and Cummins:
Cold start: Idle long enough to build air pressure/do your walk around. Then, you are good to go IF light throttle. So driving out of CG, city driving is good.
If you are parked at an freeway entrance ramp, after 2 minutes or so, go to high idle (usually with cruise control) until coolant temperature gauge is to 150 degrees F IF you need to really get into it to enter the freeway.
Cool down: Most do WAY too much idling for this. Sure, if you have just crested a mountain and pull into a rest area, let it idle for 3-4 minutes to cool down.
But, if you have driven slowly into the CG and then to your site, you are good to shut it off IMMEDIATELY. Basically you want several minutes with turbo NOT working. And in slow driving and in CG driving, you are not in the turbo.
