great truck!

PROS
Cargo Space

it’s been a great truck for taking the whole family in and it’s been a really great work truck! I’m a plumber and it helps carry all my stuff around.

CONS
Fuel Economy

right now with diesel prices being high it’s expensive to fill up. The mileage I get is pretty good for a truck just expensive to fill right now.

Maybe I got lucky, but only had 14K when I purchased and most of the plastic was still on the infotainment screens and buttons.

Has a smooth ride for a truck.
