Pickups are enjoying a strong presence in the US market, but that means competition is fierce. Practical trucks can cover uses from kid-carrier to lux-mobile, and the traditional heavyweights from Ford and GM could tow a small planet. Sadly, this leaves the 2018 Nissan Titan XD without much terrain to claim. It has its virtues, but it’s overkill for a light-duty pickup and can’t keep up with the big boys. In an industry this competitive, compromise can be a killer.
