Actual Weight Tow Vehicle (GVW) 5,930
Theoretical Tow Rating (GCVWR - Dry Weight) 8,150
Total 14,080

Dodge 3.9 liter V6
SAE Net Horsepower @ RPM 175 @ 4400
SAE Net Torque @ RPM 225 @ 3200
4 speed auto transmission
3.91 rear end ratio

Dodge rates this vehicle with a V8.

Dodge 5.2 liter V8
SAE Net Horsepower @ RPM 225 @ 4400
SAE Net Torque @ RPM 295 @ 3200

As you can see the horsepower is marginal and the torque is insufficient. If we want to travel in any area that is at all hilly the vehicle is unable to climb at all, but the fuel efficiency is good.

My goal is to keep the fuel economy while increasing it's hill climbing ability.

Thanks
