Dodge refurbished the Ram pickup for 2006, installing an all-new frame, restyling the front end and interior, and adding the Mega Cab model, currently the biggest full-size truck on the market. Dodge also offers a 345-horse/375 lb.-ft. 5.7-liter V8 engine with the same cylinder deactivation technology that is going to be available in the 2007 Chevrolet Silverado, and Dodge gives enthusiasts a Ram SRT-10 sport model equipped with the V-10 engine from the Viper sports car. The Ram’s maximum tow capacity is 9,100 pounds when properly equipped in 1500-series trim, but heavy-duty models can tackle up to 16,250 pounds.
