You can find people who have all sorts of issues with the trucks but I have a 2004 Ram 1500 with the 5.7 that I bought new and I've never had any major problems with it. The truck had to be reflashed back when it was new due to a factory firmware upgrade and then around 100,000 miles the EGR valve went out and it had to go to the dealer for that. All in all pretty minor things for 16 years of driving.
