I have a 2000 ford xlt ranger with a 4.0 v6 and a lift kit will it do good on steep mountain roads?

Roads like the white mountains in arizona if any bodys been there
and the a/c affects it please post anything that will help Thank you.

The AZ white mountains are not big or steep at all. I have been all over them in my 2 wheel drive S10 blazer.

You will have no problems at all.

But there are no gas stations, so just be sure you have a full tank of gas if you plan to stay a while and camp.

Your problem on hills won't be your power but your ability to stop on a hill smaller trucks have smaller brake packages i've found that out the hard way pay attension you should be scared before your truck
