I’m lookin at purchasing a 2017 F150 with the 3.5 turbo. Dies it have enough power to pull a 22 ft trailer with a 5000 lb tractor on it or a 20 ft camper through the Rocky Mountains?

It has the tow package and is 4x4. Also, when empty what is a realistic mpg. It has had all regular maintenance but has 172,000 miles. Anything I should look for before purchasing?

Thanks in advance for your assistance!

 

Yes,,, another vehicle !
High mileage comes with problems you don't need.
