I have a 14 Durango Limited V6. I have 60k on it. Its been trouble free, never been back to dealer. Just oil changes and 1 set of tires. The V6 is plenty for the Durango, and mine is heavy with almost all options. I have tow package and tow 3500lbs quite easily. I havent towed any heavier and probably never will since I also have a pickup. Average about 20mpg mixed, 24 hwy.
We chose it because it has more room than any of its competition (at least in 2014 when we bought it). The highlander 2nd row had more room but its 3rd row was useless. I can sit very comfy in 2rd row of Durango, and fit good in 3rd row. Im 6' 265lbs.
We've owned many Dodge trucks over the years and never had any major problems. And to be honest, I wanted the Highlander to be a better deal. But in the end, the Durango was by far the best deal in 3 row SUV's for us. Price and practicality.
In June I bought a new pickup. Again, IMO the Ram was probably the best deal, price and practicality wise, but I ended up buying a Ford just because I wanted something different. No regrets, but I really believe I would have been happy either way. Though my Ford has developed a rattle that is annoying the heck out of me. I think its the pano sunroof.
