Overall, not a bad truck, but not the greatest. It's got tons of power, and has really good fuel mileage at the same time(22 mpg). The interior is ok, except for that cheap plastic look. Its a rough ride though, but its a one tonne. The odd sized tires are bad too, go for 16's again. Also, the body paneling is very thin, you look at it, its dented. I want to get a new truck because the 2004 and 2005 Rams were the worst when it comes to reliability, proved that one with this truck. It will probably be a new 2008 Dodge Ram 4500 or a GMC 3500. I hear those trucks aren't too bad.
The Cummins, what do you expect? Its a really good motor, but the truck itself is garbage for 2004 and 2005.
This isn't the most reliable truck. It put us on the side of the road three times. The fuel pump went, the universal joint and its starting to go again, and the injector lines split. The rear door locks dont work and rear driver side window too. This is a wiring harness problem Dodge is famous for.
