Thanks ToolmanJohn!
How do I calculate the ft-lb capacity? I am currently looking at a Jeep Grand Cherokee with a 5.7L v8 Hemi engine and towing capacity of 7200lbs but I have no idea how to calculate the Lb-ft thing! thanks for all the help here!! i REALLY appreciate it - its a steep learning curve for me right now! smiles Renata |

Check the manufacturer's website for the hp and torque ratings. When shopping for a tow vehicle remember torque is more important that horsepower. And wheelbase is important too, the longer the better for stability.

I have a 172 and tow with a 2009 Xterra 4.0 L. I have been satisfied with its performance. Up hill and hot weather never is an issue. The worst is headwinds. I usuall travel 55-60 and have got 10-14 mpg. I would say my average is 11. Amazing how much drag headwinds put on it.

The engine specs can be found at most car websites. If you know the year make and model and engine sizes, the specs for horsepower and torque will be easy to find. Both Jeeps have more than enough torque, and are probably V8 engines.
Very few non-turbo gas V6 engines have more than 300 ft-lb of torque. Make certain to test drive, and get the towing specs for any vehicle you have an interest in.

Yes it is a V8 but it is a 2002 model with close to 100k miles. The newer ones probably tow better. But this one is still OK, just like the truck better.
