Well, other than a warranty replaced shift solenoid and broken header bolts on passenger side, I love my truck. Is a 13 Outdoorsman, 6 speed quad cab. Engine is powerful, smooth, is quiet, runs I think better than new still. I drive it to work 95% of the time because it runs so good, even the old 6 speed I like, only issue with the 6 speed is on hill near my house, is steep, levels off the hill etc it sometimes searches for gear, so can lag a little, other than that, engine, transmission has been excellent. All I have done to engine is canned bulldog 91 octane tune, clean my throttle body twice a year, catch can and use pens ultra plat full synth oil, a boss 15k filter and a little lubeguard biotech every oil change. I run berrymans total fuel system high mileage cleaner, can through tank twice a year and can notice difference. I also run every 2 months some lucas fuel additive. I have a volant cai, I just need to install it. Would buy this truck again, no second thought. I also have a 500+ hp ls3 Camaro and prefer to drive the Ram, sit higher, quieter, don't have to dodge every bad spot in road.
