Bro I have 16 5.0 bought it at 19k miles in arkansas . I drove it with def for 3 months I loved the truck but felt like it was bogging down a lot . I do mainly weekend trips with fam . I deleted it with egr. Holy cow it is a totally different truck I have owned it for a year now and I haven’t had single trouble but blower motor . I do change my own oil and filters and I run rotella t6 . I get compliments all the time because of that trouble whistling bys .i have friends that have 6.7 Cummins or dmax . We do run every now and then I go head to head with em comparing the engine difference we have . Love my truck what I wanted does the work and lower note than if I bought a 6.7 or 6.6. Keep it maintained and enjoy the ride.
