Looking at a Kountry Star DP, Opinions?

I don't own a DP, but I drove Semi's OTR for 44 years and 99% of the trucks I drove had CAT engines. And I swear by them I logged over 4 million miles mostly driving with CAT engines at the worst engine I drove went over 750,000 miles before a rebuild and the best milage I got was a little over 1,200,000 miles. The other two engines I drove had to get a rebuild around 1 million miles. I drove with 4 different cat engines thru my career. Our truck shop changed the oil filter every 10,000 miles and changed oil and filter every 20,000 miles on these CAT engines. Whenever my truck went in for repairs I was punished by having to drive the spare truck and it was powered by Cummins!
