On my 2011 Ram 3500 and about 77,000 miles:
Been a great truck and never has left me stranded.
Issues:
Sat Radio the presets started changing on their own, replaced under warranty.
Had a slight hiss in the power steering, they replaced under warranty a very small leak in the line.
Still orginal brakes, batteries, etc...
Got 38K miles on the factory General tires, now almost 40K miles on Goodyear Duratracs
Things I don't like:
Mileage basically sucks. But I did everything wrong: ordered 4.10 gears on a heavy loaded up crew cab truck with add-ons added, leveling kit, lights, camper tiedown, airbags, Superhitch, Supersprings, Transfer Flow replacement 60gallon tank, etc...
14.5 at 70MPH empty, maybe 15 at 65MPH
11 with Truck Camper on going 60-65
9.5-10 with truck Camper plus enclosed trailer.
Too frequent of oil changes from the idiot light.
Also don't like the costs of all the maintance items recommended.
