Big truck styling, stout towing and payload capacities are hallmarks of the Ram's Heavy Duty line. But perhaps the best hauling feature is its monster towing capacity, which tops out among its competitors.

The 2010 Ram pickups come with a system that automatically regulates diesel emissions. This sets the Ram apart from other work trucks, which call for diesel exhaust fluid every 5,000 miles to keep emissions under legal limits.

Among its interior upgrades, the Ram's truck cab offers more space for rear legroom and better quality materials on the dashboard, instrument panel and door trim. A navigation system, leather trim, heated front and rear seats and steering wheel are available as luxury options.
