I was reading somewhere that these cummins need to be run HARD once in a while. The truck in my daily driver and sees 90% of the time 1800-2000 RPMS. It rarely sees more unless I get in it. I dont tow my boat that often and my 5th wheel sits at my deer lease year round. Should I just romp it getting on the expressway once in a while ?

 

I'd romp it as often as possible,& tell your wife you need to tow the boat more often.Go fishing every weekend.You have my permission.
