5.2 vs 5.9 ram pros and cons ??

If your going to pull a car/trailer with it, I would go for a 5.9. They offer more bottom end torque, which you will appreciate when loaded. Also, the 5.2 will probably be harder on gas when pulling heavy loads because of the lack of torque, you will need to get in the gas a little more to move the load up hills and from stops. Both engines are very good engines.
