I just purchased my first ED. It's a 2016 Ram Limited with 110k on it. All service since new has been done by the Texas dealer. Truck was owned by a doctor who always had everything done on time. Are there any recommendations as to what I should do to see 300k miles out of this? I'm not going to the dealer as I have my own lift and love to get my hands dirty. I love the truck, I've put 3k miles on it and intend to tow a 7000 pound trailer from Arizona to Rocky Point Mexico 3 or 4 times a year to fish and drink beer.
