I get where your at, these are money decisions, Ive decided to go GMC with the LZ0 Duramax, I like Rams also but they seem to have slid on quality on current gen, every OEM goes through these cycles, my decision was based on I plan on doing some North American travel, I live in the country so the engine can reach its proper operating temp and I can do much of my own maintenance, but not major, there are a few things I don't like about the GM such as the oil belt in the back of the engine, but its not a deal breaker, there has been a few electrical problems, but many problems have been ironed out, I don't have a problem with a slightly higher maintenance costs such as fuel filter more expensive oil, additives and keeping the oil and fuel system clean, as for Ram Im assuming you want the 5.7, the 5.7 has been a powerful reliable engine, I have an 07 which was the first year of direct injection and I believe MDS, the whole powertrain has been flawless, it been maintained and worn out parts replaced, Ive never been left stranded and truck has never seen a tow hook, the newer 5.7's are getting many reports of exhaust manifold bolts breaking, lifter tick, cam problems and a slew of electrical problems, Ive been is a Ram Limited with e-torque, the start stop worked flawlessly, and I hate start stop systems, the large infotainment system worked kind of funky, the e-torque parts replacement costs are going to be way north if you keep the truck for years after warranty, mind you diesel parts are going to be expensive also.
